Hi,
I'm seeing some weird performance problem with a custom skin. I didn't write the skin myself, I got it on the Internet and modified it to my uses.
The performance is ok when using the default monobook skin. My performance test consist of clicking on the links of the web page repeatedly. With monobook the web site is pretty responsive, pages come back under a second.
However with the custom skin, the pages take about 2-3 seconds to render.
I tried putting Squid in front of it but performance is still poor. I tried analyzing the logs, and my only clue is that the custom skins invokes index.php a lot more than monobook. I don't think the performance lies in the custom skin, however if you need it I'll email it.
Here are the logs when I click 'Main Page' (my website replaced with 'foo.com')
