What’s the Difference Between WP Super Cache & WP3 Cache?
I just switched WP Super Cache for WP3 Cache and now I’m scared I made a mistake. It definitely speeded up my website, with 2,000 videos on it, but I’m now getting weird messages on my Dashboard… and as I look at all the choices… uh-oh, I’m clueless as to what I’m supposed to be doing with it.
Looks like a big learning curve… did I do an uh-oh or not?

Robin and Kristi. With some frustration of lag on my sites, I’ve been curious about the same thing and considered doing some comparisons. I did a search and found this string which shows that it’s not an easy choice and there are a few other things that can be done in conjunction to speed things up. I wish there was a simple answer but it might be worth trying each on your site and doing a website page load time test (I may try it).

Here’s what I found:

Tom, that is a great article or thread or whatever it is… It’s full of great info and I’m feeling better about what I did already. It’s very long and I guess I’m only half way through, but when I got to the part where the everyone was asking that guy to speed up their computer’s like he did… he replied by advising everyone to go check out their site on a website he suggested first… saying that people often don’t have a problem with either plugin, but that something else is causing their slow speed problems. And until they check and fix what ever that site tells you to fix, then he just won’t work with them, as he’s found people get attached to the weirdest self-defeating plugins and kinda get irrational about it, lol.

Reeeeeally interesting article. Now I’m understanding better what it is that I’m seeing in WP3 Cache, though I’m still not sure what choices to make, I’m thinking that I need to check out that other first, lol. Got a funny feeling something totally different is my problem now. We shall see…

Thanks again!Robin Carlisle

As far as I know; W3 total cache has bigger potential for reducing the load time of your site; it’s got everything in there.

With WP Super cache you don’t have the minifying stuff but you can do that with WP Minify if you really want to. (WP minify combines javascript files to reduce load time etc).

I currently use WP Super cache, but this is only because I migrated a site with W3 total cache to a new web host and it caused a bunch of problems that couldn’t be solved by the hosting company.

That being said, most people use W3 total cache without issues and it does great for them.

I can’t stand either of those plugins. Unfortunately it costs money, but where I can I use Incapsula (business level). ( http://www.incapsula.com/&nbsp  
You don’t even know it’s there (unlike those caching plugins which interfere with everything) and it protects against spammers and hackers.
