performance issus, please help???

[w3elf]

Also,
Here are more tests:

4x 512 mb apache server, 1 nginx server( 2048 mb) :700 requests per
second
4x 2048 mb apache server, 1 nginx server( 2048 mb) :700 requests per
second

In conjuction with the data giving before, it shows that nginx is the
bottle neck. But the cpu and memory usage are very very low. I am using
"top" and sars to check activity.

Also, using and activity on apache seems to be very low as well.
