I have a process to FTP about 1800 files with 1KB-3KB each (which takes up 4KB on the disk).

The rate to transfer most files are around 6KiB/s+ and it gradually slow down to 3KiB/s+ eventually.

I tried the GUI version, it's the same problem. However, if I were to use normal Windows FTP, the performance is very fast, however, it can't handle certain numbers of files within a particular remote directory.

Is there a parameter or configuration we can use to maximize the bandwidth we have? Currently we are still on 100Mbps network.

Thanks all!

normal win behavior, seems to be fast at beginning, then slowdown
however, transfer rates in win os are especially Wink
