Internal Performance issues

I have an Apache 2.0.51 Server that sits in a DMZ. External users can
access this server without any performance issues. From the internal
network performance drops severely. All the text loads fine, even flash
objects will load fast. All Gifs, however, take forever and a day to
load. A 3k gif will take 4 or 5 seconds. Another webserver exists in
the same DMZ using IIS and there are absolutely no performance
problems. Is there anything in the apache config that may cause this
issue? The webserver logs always show 304 not modified messages, but
that is normal, right? Thanks

Have you tried from different pc's on your lan? The images are they
created dynamically by imagemagik/gd or anything?

a remote user might not see 5 seconds to load the images as being
overly long especially if it loads all the images within 5 seconds that
would be quite normal for them.

what is your firewall reporting when you access the webpage?

first thing i would do is try it remotely for myself to make sure it is
going normal speed. have you updated apache recently?

I've tried from several pc's on the LAN. Images are basic gifs under 5k
in size. They are not created dynamically. External users load time on
this page is <10 seconds. Internal Users load time on this page is
30-45 seconds. Firewall reports nothing. I temporarily swapped the
webserver out with a different machine, gave it the same IP and all was
fine. Put the Linux box back in place and it was back to slow again.
Everything is pointing to the Linux Apache Server. It has dual NICs and
I tried the 2nd NIC and still had the same problem. If I connect my
laptop to the same DMZ it loads the page in <2 seconds. I thought for
sure it was a routing problem since it worked fine on the same DMZ
until I swapped the Linux/Apache Server out with an IIS server, gave it
the same IP, and it worked great everywhere. Unfortunately I have to
use the linux/apache server instead. I've tried the latest version of
apache and still had the same problem. Thanks.

Sounds like a network config issue. Check that the networks and
routing table on the Linux-box is set up correctly (i.e. gateway(s);
see 'man route').

Also check resolf.conf and/or resolve.conf

It could be DNS issue,.. ad if your local machines aren't named in
either internal DNS or in the hosts file,.. any resolving of hte
hostnames would severely slow all requests down.

Hope this helps,
