Apache displaying massive Reading request

[khan007]

hi:
one vps server is busy these days, webpage opening very slow, sometimes can not open at all, but ping speed has not changed, online visitors about the same, 100-200 online.
From WHM, i can see a lot "?" Reading request, maybe this is the reason making the busy server, I don't know what is it and how do I terminate it??

attached a screen cap. , thanks for your help

The users you removed are consuming the server.

maybe the time between the 8 to 11 is backup time.

are you using OS 64 or 32?

BTW run "yum update" to update the server software to latest version.

Yes its 64 bit.. and yum updated.. already.
