Proftpd upload transfers slow - even local LAN
 
Edit: - See comments at bottom of post - somewhat resolved....

I've seen several posts before about this issue, but the resolution does not seem to be final. I've set the reverse DNS to off, etc., but still on a local LAN, my best FTP upload rates with FireFTP is about 350kbytes/s on a 100mbit LAN. I connect by IP, and then the web user ID, so DNS should not be an issue, nor should I be going out and transferring by the WAN.
So, the basic question is, what do others get with FTP like Fireftp on their local server? What rate should I expect?

ethtool shows auto, negotiated at 100mbits/FDX
Server and local desktop both on 192.168.3.x LAN (100Mbit/FDX)
I connect to 192.168.3.30 (server) with FireFTP, with web1_userid
Transfer is at best 350-400kBytes/sec uploading.

However, downloading same file from Web server to desktop is 4300kbytes/sec, which sounds reasonable - so it is not the NIC or server limited

Am I looking at right config file?
What else should I look for?
Does not make sense that upload is soooo slow vs download....
can anyone explain?

Thanks

Thanks everyone...

Edit: Ok, as a test I tried a simple XP Command for XP's FTP (ie DOS box). I uploaded a 66 Mbyte file at over 11Mbytes/sec in binary mode, so it is not necessarly Proftpd... Just FireFTP I assume now, but are there other FTP tools that have the same issues?

Edit:, Ok, I tried newest Firefox with newest FireFTP, and upload rates for LAN are now better, 2-25.Mbytes/s Still not as fast as download or as fast as XP's generic FTP utility, but much better...
Sorry to bother everyone...
