I tested apc with a simple helloworld.php script, and indeed there is some difference: from 2.21 1.94 msec per page, from 451 to 513 requests per second (using 
1 concurrent clients).

If you could try a standard eZ Publish install, that would be great!

This is definitely not the case here. I thought it would not work, and disabled it only to see if it could help in troubleshooting my problem - and I was 
surprised to see the list of cached files using such diverse paths...
