Instead of filling someone else's thread here is my mess:
I've tried a Core2Duo 3Ghz, 4GB RAM, 6 - 1TB Samsung drives in ZFS RAID Z1. I also did this same setup in a older P4 but with 3GB RAM with the same results. Right now I get from 60-100MB/s write speeds and about 3MB/s read. Slightly backwards if I was expecting these results.
dd shows ~165 MB/s Writes - P4 3GB
~200 MB/s Reads - P4
~190MB/s Writes - C2D 4GB
~270 Reads
My writes went up using these settings from another thread:
And in CIFS
Sendfiles and AIO is disabled currently.
The other thing that seems odd, when doing transfers writes use about 30% of the CPU - samba, with reads, its tenths of a %. The machine also has about 2.5GB's free of RAM during transfers.
