This is truly odd. I have replied several times with real info, and the
posts do not get through, but I send a test one and it does :( Anyway, it
seems to be protocol related, as nfs reads are about 70MB/sec, twice what
either cifs or samba are doing...

This is very weird. I am posting repeated messages from the list (using
different providers), and not seeing them, either sent to my address or on
the email archive. Argh...

I have a 5-disk raidz on a 3.2ghz P4 with 4GB ram. OI build 148. I set up
a cifs share and ran crystaldiskmark. The link is gigabit, and iperf both

about 62MB/sec, but reads are only about 21MB/sec! I have spent an hour
