I get around 6 MB/sec on the very same client and server hardware for these programs. (FYI, I'm back to using a 100 Mbit/sec Ethernet. I have a client with a 1 Gbit/sec link, but it's more difficult to get to and the higher speed isn't yet necessary for our purposes.) > I checked your 'DebugFast.log' file.

I have two test files, and one is 4 times the size of the other. This was indeed the 479988-byte one. Sorry about that. The DebugFast.txt file in that zip shows that the application thought it sent 479988 bytes. At any rate, the same principle applies. The NoDebugSlow capture showing 30517591 uploaded raw bytes is still much larger than would be necessary for a 479988-byte file. > If you send an SFTP file using another client, do the inter-packet timings > look the same? Well, many of the long delays are when waiting for an ACK, but of course not all. I uploaded a zip file with the capture and some supporting files to http://trac.libssh2.org/ticket/197 I used PSFTP for this upload.
