After upgrade to 2.7 - very slow (148 posts)

    Wow. You represent WordPress? That is terrible marketing sir!

    1. No, I represent myself.
    2. WordPress is free, open source software. Use it or don't use it. It makes no real difference to us.

    Something in the code is changed that causes this. Our server was not changed and worked perfectly fine with the most recent release before 2.7.

    See, a lot of people get this fundamentally wrong. You're basically saying "X is the only thing that changed, so the problem must be in X!" The problem is that that is simply not true. The changes in X might have cause the problem in Y to get triggered now, where they were not being triggered before. This is likely because X has lots of new functionality and changes. But the problem is still in Y, X cannot fix it and retain the new functionality.

    Get it? Just because it worked before WordPress 2.7 does not mean that the problem is in WordPress 2.7. WordPress now does a lot of new things that it didn't do before, and clearly, one of those new things doesn't work on your server. But the server is still where the problem is.

    Suggesting that users "switch" is just very sad and quite surprising.

    I'm always amazed at people thinking that we're under some obligation to help them above and beyond the call of duty or something, or that we're trying to push a product or anything else.

    Let's be perfectly clear here:
    -You did not pay for WordPress.
    -You are not paying anybody here for support.
    -The people here that help people are volunteers, who help people out of the kindness of their hearts.
    -And if you're not willing to diagnose your problems and get helped by those people, and instead just want to complain endlessly about how upset you are, then your problem is completely unsolvable. And in that case yes, I very well will tell you to take it elsewhere and stop using the program that you did not pay one thin dime for. Why? Because we're here to help people, and if the only way I can help you is to say "Stop using WordPress, it's not for you", then that is exactly what I will do.

    This should not be construed as insulting, and I'm not trying to be rude. I'm just stating the way it is. If you are going to refuse all the help that we can give you and reject the only possible ways that we can help you, then I'm left with no alternatives but to try help you in the only way left, which is to tell you to go to some other package that works for you.

    @Otto42
    Sorry, that's the old "game" - my provider tells me that there must be something wrong with WordPress - you are telling us that it must be something wrong with the server - period - other word: a blocked situation.

    There is one important difference: You give your provider money. You have not given WordPress or anybody else here anything.

    I have no reason or inclination to lie to you, so why are you assuming that I am?

    To switch the server or to switch the program is not a solution in my opinion.

    Then I suggest that you fix the problem on your server instead.

    My goal: To find and solve the problem. But I don't have (root) access to the server and I have only little skill in PHP.

    Then I suggest that you find somebody who can debug the issue and pay them to fix it.

    Or switch hosts to one who is more supportive of your issues. We cannot make your hosting service magically work properly.

    Yes I know, to find a problem one must have a lot of information, as much as possible. But it is not so easy to give such information - to test software and find bugs in not all users daily business.

    And that's exactly my point. We can't help you because you don't have the access or information we need to help you. We really can't even tell you what to look for. All we can do is give limited advice.

    You need your host to figure the issue out. And if they won't do that, well, then you're kinda screwed with them. Switch hosting providers to one that works properly and provides support.

    On the other side: If you have a lot of feedback about "slowness" of version 2.7 there "must be something"...

    Actually, I have not seen a lot of feedback like this. There are a couple cases I've seen of the HTTP API blocking because of sites having disabled some functions, and some people have slowness posting due to large numbers of XMLRPC ping sites in their settings, but no, the reports of this are rare.

    Seems that not all WP staff has your opinion - to my trac-report I got nice and interesting feedback and with the suggested patches we could find more details.

    Yes, I did see the trac report you posted. DD32 made a guess and got lucky with curl being part of the problem.

    However, again, the problem is on your server. If your provider is using some funky versions of curl and other software, WordPress still can't fix that. Like I said before, at best it can try to workaround your funky broken server issues.

    You're still better off switching hosts.

    The problems described here are comparible to the problems I am having since having installed WordPress 2.7. I have tried to start with a clean install instead of an upgrade, which didn't have the effect I wanted. The loading time of pages has gone from quick (as it should be) to +- 4 seconds per page.

    Downgrading to WP 2.6.x resolved my problem, so I am now back on 2.6.x.

    I also installed 2.7 on a different host, where it worked perfectly fine: quick loading times as it should be. Maybe I could be of help in solving this problem by comparing the two server settings?

    ps: great work on the 2.7 admin interface!

    Could you please tell me which version of libcurl WP 2.7 must find on the server?

    To solve the problem, SSH to your server and edit /etc/my.cnf .

    Add:

    log-slow-queries = /var/log/mysql-slow.log
    log-queries-not-using-indexes
    long_query_time = 1

    or something similar. Then install mysqlsla and parse mysql-slow.log, and it will produce some nice stuff.

    Take that information to phpmyadmin, and use EXPLAIN on the sql queries, and post THAT information here.

    Thanks for your help - but I don't have such an access to the server and can't install software.

    I try to send the information to my provider - but he told me that there is no known problem on the server (sic!).

    @ Otto,

    Same thing here Otto. Everything worked perfectly untill the installation of 2.7!!! After that the loading of the dashboard slowed down terribly. If several users experience that problem I think that calling it "NOT A WORDPRESS PROBLEM" does not really help. Allright I don 't get load times upto 5 minutes but performance has decreased considerably where a performance increase was promised. Ans please don 't misunderstand. We all appreciate the work and effort you put into answering questions here.

    Cheers Berend.

    No, I didn't try the patches you mention. I followed the link but I simply can't understand what is going on there.
    Thanks for answering, but after spending literally hours on this, I think it would be more productive for me to explore ways of going back to an earlier version of the program.

    Ok, I understand your decision. But well it would be interesting if the patch could solve your problem - perhaps this would help to find a real solution about this issue.

    I know nothing, but I could guess it could be a bad table in your database. That was what it was on one of my other wordpress sites.

    Anyways, it probably is my server, but if it is the database, then I will tell you.

    I found an other problem: With the patch loading time is better now - but changes in sidebar widgets are not stored correctly. In widget setup page the changes are displayed correctly - but when leaving the admin and going to the blog pages the changes are not displayed.

    If I use the unpatched http.php the changes are stored correctly.

    Other way round: Without the patch I am not able to update a plugin automatically - with the patch it works.

    I have the same kind of problem: after upgrading to 2.7, first it worked great. Three days ago, the admin menu started to get really slugish. Around the same time,I got the a new upgrade-mag screenm, like the ones talked about here and here.

    The strange thing is 2.7 worked flawless for a week or so. There weren't any changes on th server, at least what I know about. Any ideas?

    OK, I solved it already. Was a super-cache something.

    I've got the same problem. WP 2.6.3 was running fine. Upgrade to 2.7 and now it's take over 1 minute to load the main page whereas before it was a second or 2. And it's definitely not my server because I still have another 2.6.3 blog on that same server and it flies.

    I'm not familiar enough with this stuff to be able to diagnose the problems, but I'm on a shared linux hosting plan with 1and1 and I'm having horrible slowness with 2.7.

    And mods like Otto make me want to leave WP altogether. This seemed like such a helpful and cooperative community but his attitude has totally soured me. Telling everyone their servers are broken and funky is not helpful. Less confrontational and dramatic language would have been much more helpful.

    @DavidLari
    Thanks for your feedback - at least I get the impression that I am not alone... Additionally the answers to my questions from my provider had about the same "sound" as we could read written by Otto - not a very nice situation to be in between and to find and solve a problem...

    Noone likes to hear bad news though. Otto could wrap everything he says up in flowery language, but he'd still have to say the same thing. WP 2.7 makes use of parts of server-side technology that may fail in some environments, which is likely causing the sort of timeouts and excessive load times that you are seeing.

    Based off this thread and the bug report one of the possible issues has been discovered and is being worked on, but until it can be figured all the way out, the issue will remain. It's not really fair to blame any of the component parts, because it is only when they are all glued together that bits don't work. Likewise a lot of people were in the testing cycle and didn't notice this behaviour - it's unfortunate but some folk will always have host environments that hit upon the odd unexpected issue.

    Personally I think it might be nice to have an advanced config option that turns off all the external connectivity bits. That's help to kill some of these problems, or at least determine where they are.

    In my opinion a very helpful tool would be a logging tool which records (all sorts of) timeouts. I think with such a tool it would be easy to find functions which don't run on a specific server.

    I don't know if nightly builds have more logging facilities - I would be ready to help finding such issues - without having root access to the server.

    After a few trials I found out that in my case it was the Backlinks plugin (1.0). The popularity contest 1.3b3 had to be disabled as well. Hope this helps.

    I have the same problem. I have other WordPress installations (older ones) on the same server with no issues. The pages load fast, but the admin area can hang for minutes.

    @tin68

    I would like to help debug this... but I am not a tech wizard or anything so I may need some guidance...

    I was on version 2.something-old, and upgraded to 2.7 @home on my local machine. So I have access to php, mysql and apache on a windows XP box if someone needs me to play with server settings...

    It is slow as hell, though I noticed the slowness only happens for me in Firefox 3. Even after a clean ffox reinstall, it's still deadly slow in that browser.
    In IE7, it takes approx up to 5 seconds to load any page. This is reasonable on my (old) machine. In fact, IE7 has been consistently faster. On the other hand FFox, my preferred browser, is stupendously slow and often exceeds the 30s timeout limit, showing a php error as a result instead of loading the requested page. This behaviour is erratic / inconsistent.

    So... Could this also be a problem exacerbated by ffox's recent v3 upgrade?

    Thanks for your input - but I don't see a difference of the loading time of pages when using Firefox 3 or IE.

  26. lsoderman

    I can confirm that there is a difference between IE and FF. I have used both across multiple machines, both browsers and different themes.

    The problem is consistent. FF hangs when loading the admin pages, IE does not. The header loads, as the page title changes, but the load seems to hang somewhere thereafter.

    A stop followed by a reload usually brings the page back up quickly. But obviously, this is not the optimum mode of operation.

    Is there possibly something in the base stylesheet for the admin pages that does something different between the two browsers that would cause FF to hang?

    It seems some ppl see a difference between browsers and some don't. At my end I can DEFINITELY see a difference between IE7 and FF3. And I have to say that while the Admin pages are the biggest problem, browsing the actual site pages aren't exactly that fast either. Or maybe it's cos I'm logged in as admin while doing it.

    Anyway. In FFox, when you request a page it just sits there for ages... the browser loading bar doesn't even move until very late in the game then I see the little green squares filling across. Which looks to me as if *BEFORE* the request, something else is happening. Is it it looking through firefox's cache? If so, for what?

    I downgrade my WordPress 2.7 to 2.6.5 the difference is noticiable.
    2.7 is not working for me because of the problem mentioned here.

    WordPress should test more the new releases...

    kind regards,

    I had the same problems as described in ticket #8590 upon upgrade. Requests were being served at a rate of 2 / second EVEN with WP-Super-cache enabled.

    A downgrade to 2.6.5 yields 2.6 K requests / second again.

    Hi,
    The upgraded version 2.7 is quite slow. As and when I try to comment on a particular topic it takes lots of time. Please someone help me out.
