Hello all, I took a look at curl performance when uploading data to sftp servers; curl is internally using a fixed-size buffer, which is only refilled when completely acknowledged by sftp write function. This creates a performance bottleneck on high-latency links, as there's a pause in upload every time curl is waiting for acknowledgements.
I propose a change implemented in https://github.com/libssh2/libssh2/pull/264, where sftp write acknowledges data as soon as it is sent to the server, and checks server response when it becomes available, which may happen during sftp close. I realize that this is a breaking change - many code examples do not even check the result of sftp close, which means that a lot of code in the wild would probably break if the patch was accepted in its current form. Would a patch like that be acceptable? What needs to happen to get it accepted? Thanks, Daniel _______________________________________________ libssh2-devel https://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel
