apache 2.2.16 deadly slow

["J. Bakshi" <bakshi12@gmail.com>]

Hello list,

I have recently upgraded a debian box from old lenny to squeeze. Hence the apache has become

Server version: Apache/2.2.16 (Debian)
Server built:   Sep 29 2011 20:59:05

But... the apache has become *deadly slow*. This box has 4GB RAM with xeon processor.
And the main point apache was running just fine with its prior version 2.2.4. After upgradation
it is tooooooo sloooow. Is there any know bug or any way to improve the performance ?


Just found these from apache error log
