Hi,
Wasn't running over ssh though. The internal buffers on off-the-shelf
openssh break performance pretty seriously for long fat pipes (unless
the hpn-ssh mods have been integrated back into production openssh,
which I'd really love to hear).
no, in general they havent. which is a pity and
I have gear in Amsterdam and in San Jose. Pushing log files from
Amsterdam to San Jose through rsync seems to top out at 7Mbps even
Is rsync using ssh to move the data? ssh has its own windowing
issues. There's a high perf fix for that which you should be able
to find via google.

If I run several rsync's it goes quicker

If I run several rsync's it goes quicker so I know I have the bandwidth.

Welcome to the limitations of TCP using standard window sizes. There
is tons of documentation out on the net on how to tweak TCP
connections to maximize throughput. WAN accel appliances are very
good at doing this as well, if you don't want to mess around with
tweaking individual
