Hello,
I have C2558 Motherboard at my disposal. I crammed some HDDs in it just to look how the setup would perform with FreeNAS.
What Performance can I expect from a CPU like that?
The Setup was:
A1SRM-2558F
16GB RAM
1 to 4 HDDs (Enterprise Grade 7200rmp 2,5")
No matter how I configured my vdevs (one mirror, two mirrors in one pool, RAIDZ1, RAIDZ2), I always got only ~40MB/s read AND write speed over CIFS.
What I also did was iperf3 test. Sending to the NAS would give me only ~600MBit/s, receiving from it would give the expected 950Mbit/s wirespeed. The former also would make the CPU spin a bit, while the latter showed no load on the CPU (of the NAS).
Also it didn't make a difference if the pool was encrypted or not. I guess thats due to the AES-NI of the board.
I didn't make more tests until now.
I realize, that this is no powerful machine, but I really expected more from it. I just want to do a sanity check here in the forums: Am I expecting to much?
As it is possible for me to use the machine as FreeNAS Server with up to eight HDDs, I want to make sure that it will be a useful setup. I really would like to have wirespeed writespeeds on CIFS (syncronous writes ON).
