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 ?
Check DNS resolution for all the domains

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