What do yo mean by "which is a completely different site"?


Other things to consider:

 * make sure that every virtual host has its own log file
 * sometimes problems occur using symbolic links, turn FollowSymLinks off
 * increase the number of spare servers etc (prefork).

Most "unexplained" delays and bizarre problems in network services can be 
traced back to broken DNS stuff

And be sure dns lookups are turned off for the client IP in the logs 
(HostnameLookups off).

Several thoughts:
  1) were they ever faster, or is this new?
  2) do they have humoungous graphics (e.g., 10 pictures that are 2M each)?
  3) do they do d/b queries; if so, how fast are the queries if you
   run them from the command line?

Do you have any link to the outside in your slow pages?
On the client side, you could try yslow...

[CentOS] Debugging slow apache server?

[Roland RoLaNd]

hello,

i'm using an apache server to host 8 virtual hosts.

even though this server is local.. 7 out of these 8 virtual hosts open extremly 
slow..
it takes around 10 seconds to open a page..

though the 8th (which is a completely different site) it opens fairly fast in 
around 1 or 2 seconds tops..

i tried tailing the error_log and i found nothing ..
is there a way i could monitor wht each branch is doing and what's causing it 
to be so slow?
any suggestion ?
