Hi!

Now we apployed latest OpenAFS windows 1.5.32 update to raise speed of
OpenAFS filesapace (which works very well) I get to the slow fileservers
 in our network.

OpenAFS filserver 1.4.6 debian .deb version
Debian etch/sarge mix system
gbit line
software raid from 3-5 SATA 750 GB HDs
Dell Server dual Core Xeon 3Ghz
/vicepa on ext3

If I scp from one of the /vicepa to my workstation (linux or windows) I
obtain 25-30 MB/Sec.
If I copy files from OpenAFS space out of that /vicepa I obtain max 10
MB/sec.
While this transport is active the CPUs are only load up to 60% from
filserver.
Over all there is enough "space" in load and network to get more than 10
MB/sec via OpenAFS.
The other cell beside our has this issue, to. They run 2 virtual server
on one physical and both virtual can send out with max 10 MB/sec, as the
physical is not under 100%load that time.

Is there any limit built in?
Has anyone reached more than 10 MB/sec from debian filserver package?

My bos startline:
parm /usr/lib/openafs/fileserver -nojumbo -L -rxpck 400 -udpsize 1310720

MfG,
Lars Schimmer
