Upload speed problems

[James Knight]

I have a kinda funny problem with FlashFXP 2.0 RC2

When I upload to a certain ftp, my upload speed seldom reach 160k or above.
If I fxp from my own ftp-server to the that ftp, I easily reach 800k.

I have checked my settings so that upload speed cap is above my capacity to not run into any problems with upload cap.

(I used to get the exact same speed difference between cuteftp pro 1 and 2, where 2 was a lot faster on uploads)

Thanks for any help...
note... this is not only against one ftp, but several different I can reproduce the speed problem.

(using:
Windows 2000 Professional SP 2
No firewall
Ethernet to internet)
