Hello
I tracked down my problems to the final write. As everything above looks
ok, async is faster and there are no accidently fsync() calls I guess
it's simply the sync NFS export option that makes writing my 200 mail
mailbox last about 30s - although this hmm simply sounds unbelievable.
(I measured the write() calls with gettimeofday() and each took ~0.1s)
How do you mount and export your NFS partitions? I do with:
export: (rw,sync,no_wdelay,no_root_squash)
mount: defaults,rsize=8192,wsize=8192
wdelay/no_wdelay does not seem to have any change.
bye,
