apache performance part 2 (ubuntu/debian/linux)

i have made KeepAliveTimeout 5 and found that mod_mime_magic is not used and it does have some performance penalties .

"This module is not for every system. If your system is barely keeping up with its load or if you're performing a web server benchmark, you may not want to enable this because the processing is not free."

Also in production is good to disable mod_status and mod_info (mod_status is called for every request for getting unix time)

I have read the lighttpd vs apache thread and seems that apache 2.2 is quite fast on php requests.
For static content or flash movies lighttpd is quite fast (youtube and wikipedia are 2 examples)
