Is possible to get Gb network transfer with my setup?

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
107374182400 bytes transferred in 623.901334 secs (172101223 bytes/sec) 172 MB/sec
Read:
dd if=/mnt/RaidZ2V28/tmp.000 of=/dev/null bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 432.063252 secs (248514961 bytes/sec) 248 MB/sec

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.

I wanted to add some things that I thought were interesting pertaining to this thread.

After I got 8.2 setup again I had added USB system drive and used the SSD as cache to RaidZ2. I was getting the Writes and Read from the most recent test, maybe a little better. But I saw improvement over CIFS. I was pushing close to over 100 MB/s for read and write. For the Read which was suck at 70 MB/s would slow creepy up to 100 MB/s and then drop down to 70 MB/s and do it again depending on the size of file.

I eventually went back over to 8.3 alpha night release and it has the option of full disk encryption. I found my dd test for read and write went to 55 MB/s for both. So broke the RaidZ2 back down tested it without the encryption even though I did before and found that with encryption it really slows it down. Then I looked into the release 8.3 version and saw that it used the AES-NI from Intel but unfortunately my 2120T doesn't support it so I tried testing it with 2600k which does and now I'm back at 147 MB/s Write and 70 MB/s Read.

Nice testing. Good thing for me to keep in mind about the 2120T and AES-NI. Encryption is something I eventually plan to use.
