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.
