Which Word Press Cache is the better I am running about 120 autoblogs on WordPress platform on a dedicated fast server with plenty of RAM and fast processors but sometimes i found my sites does not load as fast as i want to. I have tried many different solutions including but not limited to: Varnish Cloudflare WP Cache WP Super Cache W3 Total Cache Amazon S3 & Cloudfront and a few others which no longer excist or just total rubish. I were until recently using mostly W3 Total cache, but found that you need to be a server or network rocket scientist to get the huge list of options just right. I also discovered a huge error log with most W3Total Cache Page cache errors. I contacted there support and after about 3 weeks got a response that there is a bug : Code: In the PgCacheAdmin file: add 'require_once W3TC_INC_DIR . '/functions/url.php';' Around linenumber 219, the line right below (or above) require_once .../functions/http.php Well that fixed the problem but i was still not happy wth the load times of my sites, so i decided to ran a test using the current best cache options available. The following is how i conducted the test. I took 4 brand new domains, never used before. Changed the Nameservers on Godaddy at the same time. All 4 sites added to my server Each site on a different IP In Cpanel under : Optimize Website; I enabled on all 4 accounts : Compress all content I enabled Spam Assasin and set it to auto delete - changed from default level 5 to level 8 Created one email account on each account Installed WordPress in the Root of each account I then left it for 12 hours so the DNS can propagate. Logged into each account and updated to latest WordPress 3.3.1 I enabled on all Aksiment and deleted Hello Dolly Plugin. I changed the permlaink to the Post Name option. I kept only the default Twenty Eleven 1.2 theme and delete the other one. On each of the 4 blogs i installed a different Cache option, as follow: NEWDELHI-MEGA.COM -- No Cache OSAKA-MEGA.COM -- Hyper Cache + DB Cache Reloaded Fix CHIANGMAIMEGATRAVEL.COM -- WP Super Cache NHATRANG-MEGA.COM -- W3 Total Cache Hyper cache + DB Cache Reload Fix: Here i just selected the default settings WP Super Cache: In initially installed it with cdn support enabled and another plugin called CDN Sync tool and hooked it up to my Amazon Cloudfront account, but i noticed that for some reason it is not loading the theme files but only the site minus the theme, so i uninstalled CDN sync tool and disabled the CDN option in Super Cache and continued the test from there onwards. W3 Total Cache The following options were selected: Used Page cache ( Disk Enhanced ) Did not use Minify ( tried the auto option before but stopped as it was not helping) Did not use DB cache as it ( Used it in the past but stoped as it was causing IO bottlenecks which overloaded the server ) Used Object Cache Used Browser Cache Used Amazon Cloudfront CDN Used Varnish Did not use cloudflare After setting up all the cache's i pinged all 4 sites using http://www.pingfarm.com/ I then left it over night to get some traffic and hopefull get the cache to build up. The testing phase I used 4 different services to test the site load times, they were: tools.pingdom.com/fpt/ websiteoptimization.com iwebtool.com webwait.com/ ( made 20 calls for each test ) site-perf.com/ Below you can see the results of my 20 test The Below are load times in seconds As you can see from the above results the site with the fastest average load time after 20 test, is the site with Hyper Cache + DB Reload Fix installed. Conclusion If you are looking for a great cache option which require basically no additional configuration after installing and activating then the Hyper Cache + DB Reload Fix option is the best option. It provides you with a out of the box install and forget option. I now will test the winning option further by adding a Image resizer such as wp-smushit and look at the possibility of using this with cloudfront cdn. If you are a server Guru and know what you are doing then it might be worthwhile fine tuning W3 Total Cache as i think it hold great potential. Personally i will no longer use W3TC as i am not a server Guru, but mostly because there support is very poor and they expect you to pay somthing like $100 to help you configure the plugin WP Super cache has a good reputation and i know may people use it, but again many options to play with which also could mean many things which could be set wrong. This came second in my test and i think with a bit of configuring the results could be better - so this would be my second choice. Disclaimer: I am no way affiliated with any of the above plugins, these test are done on my server using my accounts. The results might be different for you on your server and i am sure better results can be achieved wth some of these plugins mentioned here if you know what you are doing.
