Want to improve the rsize and wsize of nfs mounted drives
Hi
we have couple of nfs mounts between various linux servers. Recently i was wondering how to improve the performance by altering the parameters "msize" and "rsize" for nfs.
In my machine i have determined the
NFSSVC_MAXBLKSIZE_V2 = 8*1024 but kernel 2.6 supports upto 32k
Optimizing NFS Performance
Please help me with below questions
1) Do i need to recompile the kernel to take 32k support
2) Does making it 32k reduces the performance of overall system
Also please let me know if there are any other optimization parameters.
Any help is much appreciated
Thanks
