ReadyNAS 2100 Performance Issues - read/write
Hi All, I have a ReadyNAS 2100 v1 [X-RAID2] and I am having performance problems with The read/write IOPs. They are about half of what they should be, and I have tried quite a few things to resolve...
I installed iperf on the NAS to see if I could isolate it to either a network problem, or a disk problem.
Here are my results with iperf running default:
[ 4] 0.0-20.0 sec 986 MBytes 413 Mbits/sec
[ 5] 0.0-20.0 sec 951 MBytes 399 Mbits/sec
[ 4] 0.0-20.0 sec 1.02 GBytes 438 Mbits/sec
[ 5] 0.0-20.0 sec 998 MBytes 418 Mbits/sec
Adjusting the TCP window size to 128 KBytes had these results:
[ 4] 0.0-20.0 sec 2.19 GBytes 940 Mbits/sec
[ 5] 0.0-20.0 sec 2.19 GBytes 939 Mbits/sec
[ 4] 0.0-20.0 sec 2.19 GBytes 939 Mbits/sec
