copy onto cifs-utils samba mount maxes out at 100KiB/s on 100Mib/s eth link
Hi, I can't get a normal lan-speed copy from debian wheezy client to
Server is WindowsXP SP3, client is debian testing (updated as at about
a week or two ago).
$ sudo mount -t cifs -o
$ rsync -vv --progress libreoffice-calc-guide_CG34-CalcGuideLO.pdf /x/
delta-transmission disabled for local transfer or --whole-file
9729872 100% 71.14MB/s 0:00:00 (xfer#1, to-check=0/1)
total: matches=0 hash_hits=0 false_alarms=0 data=9729872
sent 9731164 bytes received 31 bytes 93121.48 bytes/sec
total size is 9729872 speedup is 1.00
Please note the about 90KiB/second result above. The fastest run I got
was nearly 100KiB/second, but all runs a similar slow speed. The
client is a gigabit eth network, but the server is only 100Mib
ethernet port, so maximum speed should (and used to be) about 6 to 9
The duration of the above rsync command is also in the order of 2 minutes.
I've been experiencing this slowness over the last 5 months, and know
of no changes to the server at all - other clients (windows XP) do not
have this slowness problem.
I've tried 3 different cables, two different switch ports on one
switch, one port on a second switch (to which the server is also
directly connected to, all produce the same slow file copy result. So
it appears to be a debian configuration problem on my part.
Any help appreciated,
