Hi,
here is a small apache benchmark between RHEL 5 and RHEL 6.
RHEL 5: Requests per second: 8790.99 (11.375281 seconds)
RHEL 6: Requests per second: 4863.53 (20.561 seconds)

Try disabling atime (noatime mount option) on the partition you are
using for the webserver so the 'last accessed' stamp doesn't have to be
updated. If you are using your root partition for the webserver, you can
disable it on the specific files and directories by using 'chattr':

Also, try adding 'commit=30' to the mount options for the partition.
