Turnip of Power has an article comparing WP Super Cache to DB Cache plugins that is pretty interesting.

I’ve had WP Super Cache installed here for some time now (and at his recommendation, by the way). This plugin creates a cached copy of your site on your server which gets served up thereby minimizing the number of calls to your database and having the added benefit of making your site load faster for your visitors. I don’t really have enough visitors to worry about the database load part — you guys just don’t DIGG me enough, but want you to not have to wait for the site to load, so that’s my main goal in using the WP Super Cache plugin (although I secretly hope that one day, some day, I’ll need the Digg-proof part of it).

I’m not going to repeat Turnip’s article comparing the two plugins — he’s already done a great job of that — but rather to discuss, warn or otherwise notify my readers that if you, too, are using WP Super Cache there’s something I think you should know about it.

The creators of WP Super Cache are always tweaking it, making it a better product so to speak. I truly appreciate their efforts in this respect. This means that you get that nag about “new version of WP Super Cache” being ready for download and installation on your admin page and if you’re like me and diligent about keeping your “stuff” up to date and patched, then you click that button for the system to automatically update the files. You get the little hourglass icon for a few seconds and then it says “WP Super Cache updated” and “plugin reactivated”. Nice and easy that automatic updater is, don’t you agree?

What you don’t get told is that, although the plugin may be activated by the automatic update program, by default WP Super Cache is turned off. You have to go each and every time you update into the settings file and re-activate it.

Turned off, WP Super Cache is just tits on a boar hog….. there but serving no useful purpose.

So here’s the skinny — have a WordPress blog? Don’t have WP Super Cache? Get it as it will help your blog even if you only have 10 subscribers like me. Have WP Super Cache? GREAT! Now go and check to make sure you have that cache turned on.

And be aware (be VERY aware) that everytime you update the software you have to go and re-enable the cache.

Ok — now you know. My job is done!
