The addition of sliding window support makes gvfs sftp transfers behave more like openssh sftp file transfers, resulting a significant throughput increase for connections with moderate to high latency (see below).
The hang is being handled within one of the original bug reports, specifically: https://bugzilla.gnome.org/show_bug.cgi?id=532951. I'm testing updated patches to see if they resolve the hang. >From the referenced bug reports: == PULL == Some benchmark figures: Old behavior: Copying from local server = 6.1MB/s Copying from local server with 250ms of RTT latency = 0.251MB/s Copying many small files with 250ms of RTT latency = 0.64 files per second New behavior: Copying from local server = 13MB/s Copying from local server with 250ms of RTT latency = 6.6MB/s Copying many small files with 250ms of RTT latency = 1.24 files per second OpenSSH sftp client: Copying from local server = 14.2MB/s Copying from local server with 250ms of RTT latency = 6.4MB/s Copying many small files with 250ms of RTT latency = 1.34 files per second == PUSH == Some benchmark figures: Old behavior: Copying from local server = 6.1MB/s Copying from local server with 250ms of RTT latency = 0.249MB/s Copying many small files with 250ms of RTT latency = 0.93 files per second New behavior: Copying from local server = 12.2MB/s Copying from local server with 250ms of RTT latency = 6.2MB/s Copying many small files with 250ms of RTT latency = 1.24 files per second OpenSSH sftp client: Copying from local server = 12.8MB/s Copying from local server with 250ms of RTT latency = 6.7MB/s Copying many small files with 250ms of RTT latency = 1.33 files per second ** Bug watch added: GNOME Bug Tracker #532951 https://bugzilla.gnome.org/show_bug.cgi?id=532951 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1248763 Title: incorporate patches for sliding window support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1248763/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
