Easy Web Performance Optimization (WPO) using caching: browser, page, object, database, minify and content delivery network support.
Not sure if it works properly or not.
Havn't maed up my mind yet, but was forced to review in order to troubleshoot.
Installing this plugin seems pretty straight forward but you will most likely need advice from your hosting provider or a professional WordPress developer in order to configure it properly.
Furthermore, this plugin can really mess up the caching and cause your site to behave very strangely indeed, especially if you are using a web firewall (e.g. SiteLock) and/or your hosting provider provides varnish-based caching to your website files.
The plugin tends to leave a lot of 'garbage' in the wp-config.php and .htaccess files which stays there even after the plugin is deactivated and deleted!
This can cause some very strange behaviour on your site (this is just one example) and unless you are an experienced developer or use a host with extremely good technical support who are experienced in how WordPress works, the root cause of such behaviour will be extremely hard to pinpoint and troubleshoot.
Bottom line: unless you are a 'techie', I strongly recommend you stay away from caching plugins altogether!
If you want to increase the load speed of your site, consider using a CDN or switch to a web host that can provide fast load times.
If you are not a techie and choose to go down the caching plugin route, it is very possible you will either break your site completely or cause it to behave erratically.
Not worth the risk IMHO unless you have the know-how and time to delve into the code to fix any mess this plugin can & will leave behind.
It is a great plugin, I am using it on my site. With its help, my posts are having 100 PageSpeed grade almost always and are served very quickly, usually less than 0.2 sec for the initial html and about 0.5 sec the entire page.
Thanks, Frederic Townes!
Nevertheless, I give it only two stars, for many serious problems it has:
1. It is quite complicated to configure and very short on documentation. For this reason many people have written their versions of configuration directions. As all published directions did not work for me, I have written mine:
Nevertheless, the plugin author who knows how it really works, would have been able to explain better.
2. Minify feature uses
<link> to embed css, with plugin FAQ claiming that it is non-blocking while Google PageSpeed considers it blocking. For more details see [Link redacted] Get PageSpeed 100, Part 2.
Due to items 2 and 3, I am not using Minify feature of this plugin and using another plugin, Autoptimize, instead.
4. Cache preload is an important feature but I have not been able to make it working. In my experience, when it is enabled, it just removes cache but does not replace it with a new one. I ended up disabling it and replacing it with a cron job as I explain in [Link redacted].
5. The annoying popup that many people are complaining. (For the directions how to tame it, see [Link redacted].
IMHO each of these five major problems deserves one star off. However, I appreciate this plugin and I cannot give it the minimum of one star; thus, I give it two.
The price of a great free plugin is a super-annoying pop-up every time i make a config change in the admin.
The price of a super-annoying pop-up is a two-star review.
While I really appreciate free plugins being available, this one made me spend too much time hoping to eventually returning something, then didn't. :-/
My results after many hours of testing:
» Minify feature was causing my site to not work properly – disabled it.
» DB-cache, Object-cache – no speed gain whatsoever.
» Page cache – 1 more point in PageSpeed ... yay!
» Browser cache (set expires header) gave me the infamous "cart doesn't update issue" – disabled it.
In the end it took me ~2 days of fiddling around without getting anything done, without getting a faster page (or at least a higher score in PageSpeed).
If it works for you: Congrats! For me it didn't.
P.S.: Of course I _tried_ the following to make it work (you can read this up yourself in countless hours all over the Internet) –
» added mfunc to "Ignored comment stems" in HTML/XML section
-- Page Cache:
» added /cart/, /checkout/, /my-account/ to "Never cached pages"
» added wc_session_cookie to "Rejected cookies"
-- Database Cache:
» added /cart/, /checkout/, /my-account/ to "Never cache the following pages"
» added _wc_session_ to "Ignored query stems"
Bloated, constant popup, problems clearing cache (had to uninstall and reinstall to refresh homepage), errors galore, css problems if minified and I am sure more problems that I have forgotten. Maybe great for very big and busy sites but for smaller sites you are better looking elsewhere.
This isn't a very nice way to get more reviews.
Also, I really haven't seen my site get much faster.
After installing it breaks my site, my site is really slow and really want this to work.
Any help would be great
good but plugin not support php 5.6
