On a gigabit network, that sounds like a long time to load a 5M file.

Do you do a lot of updates on the Linux server, like creating and deleting 
thousands of files at a time? It's possible that the Linux server is just 
locking up flushing its buffers if it has a lot of RAM. Sadly, I don't know 
any sort of monitor that would actually tell you what's going on inside the 
kernel of a Linux machine. (Anyone know what the equivalent of Performance 
Monitor on Linux is?)  If your file server has RAID, maybe there's a bad 
spot on one of the disks and it retries a while before falling over to the 
other disk? Maybe check through syslog records to see?

Check the domain server's event logs around the time of a problem, and see 
if it's an authorization problem or something, where maybe you're waiting 
for a new kerberos key to access the remote file and the domain server is 
slow giving it out for some reason?
