Saw this on digg about a quick summary of PHP cache. So, I give eAccelerator a quick try. Dries has rpm package afterall. So it just a simple install, and restart Apache.

Benchmark result:
admun blog: 0.34sec -> 0.26sec
admun NUDN: 0.16sec -> 0.10sec
default nucleus: 0.048sec -> 0.017sec
wordpress: 0.092sec -> 0.043sec

I think the more SQL queries you are doing (or more complicated processing a script does), the less gain you will got. The reason is that the accelerator works by caching the compile byte code for a PHP script, so initialization overhead is reduced. But there is no real-time processing gain.

Anyhow, it still quite amazing!
