Yes we exported it async :) as confirmed by the snoop that I reported earlier. See it also below. But nothing changed. > The other thing to remember is that "cto"... > ... On the solaris client? It is not in the man mount_nfs, but it worked. However there was no performance upgrade. Also, I can't recognize it in the old traffic snoop.. I report below some of it during the write of one file from tar. ...It must be something really more crucial, for a performance upgrade of 3-5 times.. A clue seems this now: the "tar" process itself on solaris uses 4% cpu while writing on a local disk, and 40% and over while writing to the nfs disk... (not using -z gzip:) Also, mounting nfs2 seems 30% faster.. But we do not understanf the reason.
