Hi, I have a wordpress (3.1) site hosted in a shared hosting plan. Due to high traffic, I am facing performance & bandwidth issues. So, I want to implement/use any caching mechanism to serve static files. I found two popular caching plugins for wordpress, which is "Quick Cache" and "WP Super Cache". Please help me to choose the better one to use.
I would recommend to use WP Super Cache! it works good and highly supportable within all versions of WP
^^^ I see w3 Total Cache as the top reccomended product, but who truly knows what's better. Could you show us any test results?
Hmm... thank you for all your replies. The thing is I am using premium themes for most of my WP sites. Those themes uses "timthumb" script to generate the Thumbnails & other image sizes on the fly. Some times the script takes lot of CPU resource to generate the thumbnail images. Because of this I got suspended from few shared hosting services.. Can we avoid this issue by using any of the above caching plugins?...
I've tried both W3 Total Cache and WP Super Cache. Like techntuts, yayack3, and jezzz, I also recommend WP Super Cache. It's easy and does its job without any complications. I've seen many people, like KimiGermany, claim to not have experienced any improvements after installing W3 Total Cache.
I would personally recommend using WP Hyper cache. It is the lightest caching plugin and has a very good performance. I had a horrible time with WP Total cache.
First I used W3 Total cache and I was using Themeforest's news cast theme, when the traffic is low, it served better but day by day after my traffic increased I got lot of problems. When i login as admin my website loaded very slowly. Often i get logged out due to it's clash with postplugin library plugin. So then switched over to wp supercache, as it's meant for speed(whereas wp total cache reduces server load more than delivering speed) but then still when i login, post and see preview of posted blog my website got dead often, I disabled every plugin, switched over themes. But now I'm comfortably using Quick-Cache with 45 Plugins active on Thesis Theme. If you want you can test my website at lenzfire dot com
Performance, who knows; but after trying them all, I like the Quick Cache interface better and Total Cache always messes with my sites in annoying ways, such as still caching even after I've told it not to. So right now I'm preferring Quick Cache all together.
I totally recomend W3C Total Cache. It's the best plugin ever. But you need to know how to configure it. Mashable.com use W3C total cache. Other big sites based on WP use it.
