So, I've done a lot additional testing and here are the results.
We currently have a GlobalScape FTP Server in our network up and
running. I ran two transfers to it, each with 35 small files, one in
active and one in passive mode. Both transfers took approx 3 seconds to
complete. Then I took Apache FTPServer and installed it on the same
machine and ran the same tests to it. Passive took 3 seconds and active
took around 156 seconds. This test eliminates my theory that it's
network or pc related.
Below is a small clip from the log file during the active transfer that
took a long time.

Command PORT okay.

Transfer complete.
As you can see there is a 5 second delay in there only during Active
connections. If you need any additional information please let me know.
Thanks in advance!!

Has anyone noticed a difference in performance between FTPing in Active mode
vs. Passive mode?
I have two laptops on the same network:
1) Client - Windows Vista, firewall disabled, using FileZilla
2) Apache FTPServer - Windows XP, firewall disabled
When FileZilla is set to passive it is relatively fast. When I switch it to
active it is 2 times to 3 times slower.
I've done quite a bit of research and playing around but I haven't been able
to determine why. I'm hoping someone can shed some light on this for me...
Do you see the same behavior with other clients? I can't see anything
obvious in our code that would cause this but I don't have any numbers
to back that we don't have a problem in this area.
