High CPU load on page access

[SunboX]

Ich someone accesses the index page, it has a high CPU load (94% on Raspberry Pi). So the page loads several seconds. Useless on a Raspberry Pi. I can't understand why, looks like a static page.

The browser on the index page takes high CPU? or the server when and index page is loaded?

[SunboX]

The server when the page did load. Try to run it on a Raspberry Pi. They are cheap.

Weird, someone used to run sharefest on RPi a while ago and said the CPU is incredibly low.
Can you profile it?
