Hooray its not hardware issue! I didn't think so nothing indicated it was and the whole build is brand new but never know with HD's DOA or a intermittent problem. Used ESD strap and mat as well for possible user error.
After fresh install of x64 8.2 I built raidZ2 again and did new dd test:
Write:
dd if=/dev/zero of=/mnt/RaidZ2/tmp.000 bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 691.696476 secs (155233092 bytes/sec) 155 MB/sec
Read:
dd if=/mnt/RaidZ2/tmp.000 of=/dev/null bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 407.047292 secs (263787979 bytes/sec) 263 MB/sec
CIFS test though:
100 MB/sec Write , 70 MB/sec Read
Now I get why this is funny as Joe said but it was good to fix my dd problem.
So I need to find out how to tweak Samba/CIFS and maybe I can get a better result.
Tested 8.3 and dd results are:
Write:
dd if=/dev/zero of=/mnt/RaidZ2V28/tmp.000 bs=2048k count=50k
51200+0 records in
51200+0 records out

CIFS were same in 8.3 as well.
Anyone have any clue what my software configuration problem could of been? Anyways I will eventually go step by step and test to see on what configuration could of cause the problem.
