The almost common answer was:

The NFS speed for writing is much slower, because

all writes have to wait for the disk write to complete.

Try ascync writes to NFS clients.

aga@Comtech.com sent me a patch to apply to allow this.

wawers@limone.lif.de suggested to reduce wsize on the PC-site

to 1k. I will try this first.

If anyone wants, I can send him/her all answers.

A question about this: How do you think about enabling async writes?

Thanks to following people:
