[Bug 250517] Re: gvfs performs slowly on bulk sftp transfers
Yes, the problem still exists and has some very weird properties. Using the sftp cli I get speeds up to 800kb/s which is the max due to overhead and others services that eat up upload speed. Using nautilus gvfs, I get under the same conditions 250 - 350 kb/s. The strange thing is thoug, that when I copy another file simultaniously it reaches the same speed as the first one, even a bit faster. The maximum is reached with 3 or 4 parallel downloads, depending on the load of the uplink.

I also ran into the same problem on LUbuntu 10.04, which increases big file transfers times with hours. Could it be that sftp from Nautilus selects a different cipher for its encryption?

[Bug 250517] Re: gvfs performs slowly on bulk sftp transfers
Reading the upstream bug ( https://bugzilla.gnome.org/show_bug.cgi?id=523015 ) suggests that the slowness is because when nautilus writes a file via gvfs, it writes a buffer, then waits for gvfs to confirm the write, then sends more data, waits for a reply, etc. It seems like it is a bit of a design flaw, but it might be hard to fix (see comment 2) since both nautilus and the sftp backend are using the API as designed. It doesn't look like anyone is working on it.

I don't have two Intrepid machines to test this further, but I can test Hardy-to-Intrepid if it would help. With the exception of the file operations dialogue, all line-speed measurements were taken with iptraf. Wireless G @ 54M sftp peak: 1229 KB/s. Average is about 1 MB/s sftp reports transfer speeds between 900 KB/s and 1.1 MB/s gvfs-copy peak: 1174 KB/s. Average is about 900 KB/s nautilus copy: Peak 12153 KB/s. Average is about 900 KB/s File operations dialogue reports transfer speed as between 700 and 800 KB/s Conclusion: wireless isn't fast enough to properly test this. Transfer rates are in the same ballpark. Hardy and Intrepid have resolved the worst of Gutsy's gvfs problems, for wireless, at least. The file operations dialogue seems to use some sort of transfer speed averaging function to smooth out the fluctuations in speed, but it needs work. I haven't looked at the code, but I would imagine that making the sampling period smaller (time or bytes transferred...which one work work better, I'm not sure). Of course, CPU usage will go up if the sampling period is too small... Maybe keep the refresh rate of the transfer speed function the same, but have it look at the last MB transferred, instead of however it's doing it now (I suspect it's looking at more than just 1 MB) At any rate, John, could you please test using sftp on your gigabit ethernet?

ii gvfs1.0.2-0ubuntu2 ii gvfs-backends 1.0.2-0ubuntu2 ii openssh-client 1:5.1p1-3ubuntu1 Copying a 1018MB file from an ubuntu 8.10 (Intrepid) desktop to a Debian 4.0 (Etch) server across our LAN (via 100Mbps ethernet): scp command line is around 11.1MB/s (as reported by scp) gvfs-copy to sftp://; location: 8.6MB/s (as calculated by measuring the Sent bytes on the ethernet interface) copying to the same location in nautilus by using sftp://; location: 4.1MB/s (as reported by nautilus copy dialog) but 8.5MB/s as calculated by measuring Sent bytes on eth interface! Copying a 400MB file from ubuntu 8.10 to debian 4.0 via 1000Mbps ethernet: scp command line = 71MB/s gvfs-copy = 31.9MB/s (measuring eth0 sent traffic) nautilus = 30MB/s (measuring eth0 sent traffic), but copy dialog claims 14.6MB/s So there are 2 problems - gvfs is significantly slower than scp for doing copies, and nautilus is incorrectly calculating the copying speed. -- gvfs performs slowly on bulk sftp transfers https://bugs.launchpad.net/bugs/250517 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 250517] Re: gvfs performs slowly on bulk sftp transfers
While not the same speed, I've noticed an improvement recently (using Intrepid).

I'd like to confirm that this problem is even worse on a wireless network. -- gvfs performs slowly on bulk sftp transfers https://bugs.launchpad.net/bugs/250517 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
