To be more specific, I trust you're speaking about SFTP download performance, right? I recall someone mentioning that it does upload a lot faster. > This is a quite important for our project too and may be we could find some > resources to help you. Do you have any estimation ? I don't know of any detailed or close analyzis done on this issue. There have been speculations on the SSH windowing code and that SFTP "pipelining" (kind of) are keys to it, but I don't think we have any hard facts to back those up. The resources we need are: time spent on this by clueful persons. These persons could then test performance, note details, analyze network packets, read code, read SSH/SFTP specs and see what libssh2 does wrong at this point and how to fix these issues. Estimating what time it'll take depends a lot on the specific persons, and since no detailed analysis has been done yet it is very tricky to estimate the time it'll take to address the issues that it should reveal. NOTE: these are my personal opinions and estimates. I don't write on the behalf of anyone else. -- / daniel.haxx.se ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
