Topic "Upload and download of multiple files terribly slow"

Author Message

I know, this has been discussed a lot, but fact is, the problem is still not fixed. I can upload / download with max speed if I download only a single file, but my speed will go down to 3 bytes(!) per second, as soon as I try up- or downloading multiple files.
I have tried this on three different servers now and on all three show the same behavior. I tried changing the number of simultaneous processed files, no change. I have tried SFTP and FTP with TLS and without, no luck.
I also found out, that speed loss is diretly linked to the amount of files processed. One file will show no loss at all, two will show a little loss, three some more and so on...
I love WinSCP but being forced to pack everything into a single zip, to be able to work with it, is becoming frustrating.

Do you mean that when there are three parallel transfers ongoing, the total transfer speed of these three is lower than a transfer speed of single transfer?
