I am facing the same problem since I updated to WP 4.6. However, only wp-admin gives me slow time. My website is running fine. WP-dashboard is extremely slow lately. Also, I am not using WP-Knowledgebase. I can’t figure out which plugin is slowing it down.
I too am experiencing severe problems since installing 4.6, if anyone can help i’d be extremely grateful
Hey sabrownless & evan,
I just optimized my website and database tables using WP-Optimize. [https://wordpress.org/plugins/wp-optimize/]
Now the dashboard is responding quickly. Maybe, optimizing the database tables did the trick. I haven’t optimized it for long so I gave it a shot.
Maybe it will help you too. However, make sure you backup everything before using the plugin, just in case anything goes wrong. It has high ratings as well, so it is a safe plugin. If you try it let me know if it worked for you.
Anyway, here’s my website: http://www.androidsage.com/
Cheers!
I am to in the same boat, dashboard is fine but site is a lot lot slower – we had 2-3 second load time on gt metrix and now it is awful. Wp Optimize breaks my site… It was all working fine before 4.6 update. Can please have some help?

I am having the same issue. Back-end is slow, front-end is fine. Happened after updating to 4.6. My database is pretty small, so I don’t think that is a reasonable solution. The network tab in Chrome’s developer tools is showing roughly 25 seconds to load index.php, edit.php, themes.php etc. so I’m guessing it’s a code issue.
Ok. I mainly had this issue when I logged into my WP admin because it used a lot of server resources mainly CPU, entry processes, etc. Here is what I did and my WP-admin/backend is fast as it used to be. I deactivated some plugins and removed some unused plugins. What I found was that I had BBpress setup on my website and made a forum which did not actually work well for my website so I removed it and suddenly my website was fast. It had its own login screen and whenever I tried logging in, it redirected me to BB press login. So maybe it has login problems. Later removed a bunch of unused plugins. So I would recommend removing any plugin that messes up with the login section. Deactivate all plugins if you can and reactivate one by one. WP-Optimize was a temporary solution but it did help in some way. Also, I recommend using WP-Fastest cache and not using the option Preload cache in any caching plugin unless u r sure. Of course, caching plugin helps and also recommend using CDN like Cloudflare, Incapsula CDN, etc. I am using Incapsula due to some reasons. They are free to start with.
I experience exactly the same problem with 2 sites that I updated recently to WP 4.6 ! It is worst when I log in on back-end. Physical Memory Usage and I/O Usage goes crazy! I really do not know what to do! I’m quite sure it is about the 4.6 update, otherwise it is a really strage coincidence. I hope there will be a bug-fix from wordpress very soon.
My sites are

I couldn’t bear the performance issue any more, so I installed Query Monitor. As I suspected, MySQL queries was not the problem. According to Query Monitory my queries are executing in ~0.01 seconds so that can be ruled out. My HTTP requests on the other hand were taking about 1 second each. With roughly 20 HTTP requests being executing that explains why it’s so slow.
The culprit turned out to be Gravity Forms (plus add-ons). With Gravity Forms (and all add-ons) disabled my WP back-end is loading in less than 1 second. After enabling Gravity Forms by itself load times jumped to 7+ seconds, after enabling some add-ons back to 20 seconds.
It looks like the HTTP POST requests to https://www.gravityhelp.com/wp-content/plugins/gravitymanager/version.php are taking about 1 second each.
I’m still not sure why this would be. Maybe someone from GF support will have the answer. I will post back here when they respond.

Same problem here. Have found that Gravity Forms slows the admin load times down byt ~10 seconds.
I can also confirm that downgrading to WP 4.5.3 solves the Gravity Forms issue
@fried_eggz Thanks, may I ask what your server set-up is?
@robsticles: Sure!
Server: Ubuntu 14.04.5 LTS
PHP-version: 5.5.9
MySQL-version: 5.6.31
Apache-version: 2.4.7
WordPress-version: 4.5.3
Gravity Forms Version: 2.0.6
The above setup works. Upgrading WP to 4.6 slows the site down 20 times when Gravity Forms is active

@fried_eggz Thanks for the info, nearly identical to mine. Looks like the downgrade will have to do for now 🙂
Yes. Im going with the downgrade for now as well. Someone should open a support issue with Rocket Genious, if there isn’t one already.
@fried_eggz I did, support pointed to either theme or server configuration because they are not able to reproduce the error on their side. They suspect the cache is being corrupted somehow. They also asked me to try with a default theme, but I haven’t had the time yet.
