I have an ftp server configured for passive mode. It works fine regarding beeing able to connect to it.

But at first it seemed that some ftp clients got quite serious performance issues, including myself from my testing site using FlashFXP.
I have a 10mbit internet connection but ftp was somehow limited to 170KB/s
per user instead of the roughly 1000KB/s that is used normally. I had 2
different users try the ftp, both using FlashFXP and they were both given
exactly 170KB/s. I tried all kinds of stuff in order to solve this. Then all
of a sudden one user logs on and it all works perfectly, no performance
issues. I was baffled, I then tried ftp from IE 7 from my testing site and
it all worked perfectly, I was also using flashfxp before?! This is quite
strange since I recently installed my ISA 2006 server; the old firewall had no
problems with FlashFXP and the ftp server. Is FlashFXP doing something strange that IE7 doesn't do that the ISA 2006 server picks up on? Any ideas`? The logs show nothing.

Sometimes FlashFXP needs to be optimized for your network setup. Basically this means adjusting the TCP/IP Buffer Size option within FlashFXP

Options > Preferences > Connection > TCP/IP Buffer Size

My first suggestion would be to try (default), and then work your way up from there.

When changing this setting special care must be taken, It can only be changed while disconnected from all sites. If you are connected to a site the change wont take effect until you restart FlashFXP.

(For my network setup a 32k send & receive buffer seems to work best)

Thanks for your answer, it seems it was Gene6 that was the culprit. Changing server to Serv-U took care of it.
