/mnt/backup             192.168.0.3(rw,sync,no_root_squash)

mounted on the client with
server:/home/puchu      /mnt/server/home        nfs           rw,tcp                    0 0
server:/mnt/data        /mnt/server/data        nfs           rw,tcp                    0 0

i can scp with 1.2MB/sec up to the nfs server and down with .5MB

dont know what could be the problem.....

Reproducible: Always
Comment 1 Jakub Moc (RETIRED) gentoo-dev 2007-03-11 21:18:44 UTC 
Tried with a newer kernel?
Comment 2 Herbert Wantesh 2007-03-12 07:42:55 UTC 
updated kernel .. problem fixed ... i think it was a traffic shaping problem...
Comment 3 Jakub Moc (RETIRED) gentoo-dev 2007-03-12 07:44:46 UTC 
Thanks for reporting back...
