Wrong, I believe.

sync vs async is chosen on the client and Linux now supports this.  I
believe Linux NFS caching behavior on the server has also been significantly
improved.

Linux also supports NFSv3 and, if you're insane, TCP.

Linux NFS performance is generally very good these days.  It has had it's
bad times with reiserfs NFS performance being something that notably
sucked badly for a while recently, but in general it's been good for some
time.

When Linux NFS was userspace, yes, it sucked.  But since people have
been working on making it fast in the kernel, it's become rather nice.

Of course, for optimum performance use 9k MTU and then your NFS speed
will absolutely rock :-)

Or, eBay a NetApp.
