SBB Posted August 20, 2011 Share Posted August 20, 2011 Hi all, I'm having some problems with very low read speeds from my unRAID setup - when copying to my cache drive, the speed is great, around 70mbyte/sec. But when I read from the array the speed is only 3-4mbyte/sec, even when only copying 1 file at a time. Parity check speed also seems reasonable at 45mb/sec. My setup is as in my signature, the drives are connected as follows: Parity - WD EARS 2TB with alignment jumper - Connected to motherboard SATA Cache - 500GB Seagate 7200.12 - Connected to motherboard SATA Rest of the drives are split across the motherboard and a Raidcore PCI-X card I have installed (on a PCI-X slot) I am using a vanilla install of 5.0-beta11 Thanks in advance for any help!

SBB Posted August 20, 2011 Author Share Posted August 20, 2011 For some reason changing the network cable fixed it for a few minutes, then the system "froze" for a couple of minutes (I couldnt access it at all) and then came back with the same slow speeds ... Any ideas? Quote Link to comment
SBB Posted August 20, 2011 Author Share Posted August 20, 2011 ARGH this makes no sense: I tried with a direct cable connection between my PC and unraid server ... full speed. Using switch, slow speed. So I figured there must be a problem with the switch ... so I ran iperf between unraid and my PC over the switch and these were the results: Anyone got any ideas, this problem has totally got me stumped!

sonata31380 Posted August 21, 2011 Share Posted August 21, 2011 I also try to use iperf When I execute the command: iperf-c hcsrv1 I get the message: connect failed: Connection refused Quote Link to comment
thejinx0r Posted August 21, 2011 Share Posted August 21, 2011 You also have to do "iperf -s" on the unraid server. Quote Link to comment
