XCache – A booster for WordPress

I was not pleased with the results of my database tweaks. So I looked further to improve the performance of this blog and stumbled upon XCache. Developed by the same people that created lighttpd, XCache is a PHP opcode cacher that greatly improves WordPress performance.

Using the same Java program I used in my previous tests, I queried the website 500 times and packed the data into a graph. This is what showed up:

Now that is what I am talking about! The query time is nearly three times as fast as before.

I am still looking into other cachers like Alternative PHP Cache (APC), but I like xcache so far.
