I use cable capable up to 200Kbytes/sec approx upload speeds but best I get with winscp is 20-30k, file download speeds are fast
and not a problem. I'm wondering what parameters govern the speed of file upload, winscp? or winxp registry? or some access/speed restrictions on remote linux server, or issues between windows and linux? Any suggestions appreciated.

thanks

Disparity between download and upload speed is strange. One one the reasons can be too low SSH channel window on the server server. But this is just a wild guess. Have you tried other SFTP client?

Hi,

Yes, just tested there wsftp_le and got 300kb/sec on file upload,
while winscp is giving just less than 30Kb/sec upload speeds. Could it be something server side is keeping ssh down to that slow upload speed, could it have anything to do with file/resume upload feature slowing it down? Anything I need to check on the server side?

AFAIK WSFTP_LE does not support SFTP, does it?

nope, but I have a correction to make: WSFTP_LE was measuring bits/sec and not bytes/sec, changed to bytes/sec it registers
about 30-32 kb/sec, close enough to winscp. Overall, file upload
using winscp and SFTP and WSFTP_LE are slow, dunno why.

and no,WSFTP_LE doesn't support SFTP.

thanks again

So you aren't comparing the same thing. But that's a huge performance difference, regardless.

Was there ever any resolution to this?
