Hi Bent,
Have you tried the latest bz321111 kernel from Johnny?
http://people.centos.org/hughesjr/kernel/5/
I have kind of lost faith in RH kernels as far as NFS performance is concerned - and yes, I know that the bz321111 issue is supposedly solved in 5.2 but until we can positively confirm that ourselves I ain't letting it near our production servers
Yes I did, however now that you mention it, when i did first time i had two issues one of performance that i am not getting the required performance in terms of bandwidth, and by applying the standard RHEL4 kernel network parameters that did fix it, now i am left with that scalability issue
regards
Walid
