TCP Out of Order Packets? Help!

[Joseph Kubik]

You may want to try a network test tool like netperf or Ixia's
Q-check. Ftp uses the disk and network at the same time.

Given that, Is the performance worse on a send or receive?
If you send a large file, does it slowly degrade?
Are all of the computers plugged into the router, or is there another
switch / hub?
If you exclude the router, does it effect the perfomance?
