My system has the following specs :
8 GB RAM
2 x 160 GB SATA HDDs
2 x 200 GB SATA HDDs
Intel Core 2 Duo CPU (E5400)
And Freenas 9.2.1.x , not 100% sure of version number at this point.
Have setup these drives in a ZFS RAID 10 Volume and I'm accessing this using iSCSI. I get about 55MB/s when reading from the iSCSI drive (HDTune benchmark). I can see that each disk reads between 15 and 12 MB/s so they are not running at speed. (a single disk can do +-45MB/s) Aslo the CPU is below 40% and there is about 1GB RAM free with no swap space being used. Surely with this hardware I should be getting +- 90MB/s ...
What settings do I need to have a look at ? Also are there any test I can run locally on Freenas to check if there is something wrong with a disk or a benchmark to determine where a bottleneck is if any? (which I doubt)
Please advise ...
p.s : Just telling me to buy a overkill system is not advice. This setup will get 90MB/s on a Windows system with software raid which is the performance I am looking to get.
