I spent some time working on Viper Cache last night. It's going to get a new name at some point, but it's close to being done. I'm going to test it on this site for a while and see if I can iron out any bugs. ...
Well, this is interesting. I gave a few individuals an alpha version of the Viper Cache plugin I've been working on. It has just been reviewed on Anieto2k, one of the largest plugin sites. The author compared it against all the Wordpress plugins available today for caching. The full write-up is available here.

There are a lot of different ways you can increase the speed of your website, even if you have relatively cheap hosting. If you're lucky, your blogging platform already has a caching engine built in (Drupal does). If you're unlucky, and running something like Wordpress, you have to do a bit more work.

The problem with the first item is that even if you have a cache hit, the entire Wordpress PHP core is parsed and partially executed. What that means is the caching system will always be limited by how fast the PHP parser is on the host ...
