In the hunt for oddities regarding the new IFS Windows client I have
observed a problem causing bad performance, and hopefully someone has
some idea about what is going on.
Environment:
Server: OpenAFS 1.4.12.1, CentOS 5.3
Client: Windows 7, OpenAFS 1.7.1
Any hints anyone? I think this smells as traffic shaping due to the
quite exact transmit rate but
since the QoS module is uninstalled and the behaviour is seen on the
windows network interface
I have no clue where it may be.
Not really a idea or anything, but:
- encryption enabled or disabled on client?
Disabled.
- local cache on client on slow harddrive?
No, state-of-the-art HP workstation. Note that this is more-or-less the
behaviour
of all our Win7 machines with the IFS client, all of them are really new
hardware.
Our current setup does show 20-40 MB/sec with OpenAFS 1.7.1 on 64bit
system, depending on the server.
Yes, and that is what we expect also, therefore I am investigating this.

A side note: Going via a SMB-AFS gateway on the same network gives
significantly better
performance.
