Do you have any hint where I could start to debug this? I already made shure, that NFSv3 is used in any case.
I already read the FAQ. rsize and wsize values of the client are already set to 8192 and NFS over TCP did not solve the Problem either :(
As I already said, all I did change on the Server is Kernel Versions. The whole stuff works perfect with Kernel 2.4.31 and is dead slow starting from Kernel 2.6.9 (the first 2.6 Kernel I tried to use) to Kernel 2.6.11.10 (the latest 2.6 Kernel I tried to use). It is slow because nfsd seems to eat all my CPU when NFS is in heavy use.
B10 in the FAQ is exactly the Problem I seem to have, but the solutions proposed do net seem to match my case :(
I neighter have some ancient Kernel (<= 2.4.20) nor do I have a complex network setup (just one single switch between the client and the Server machine).
BTW, both machines are x86-32 architecture.

What are your exports (cat /etc/exports on server) and mount (cat /etc/mtab on client) settings?
