Post your performance results
I thought it might be interesting to see what kind of performance everyone is getting with IO Meter so that we can compare what we're getting. So I thought we could all post our results in this thread...

Tonight, i was transfering files with ftp while sabnzbd was DLing at full speed (2MB/s), the speed was 100+ MB/s. And on the other hand, i can't seen to exceed 50-60MB/s with CIFS.
Tonight i was curious and ran some tests with the top command running on ssh, and the issue with Dling and SMB CIFS is really frustrating.
IOmeter ran at 55MB/s on both read and write.
The read speed was very constant with a CPU load under 30%.
The write speed was erratic (between 20-30MB/s and 90MB/s averaging 50-55MB/s), which saturates the nas CPU (the SMB process and raid5 process both take turn using the CPU).
Where is the restraint on read speed using smb ?
FYI, using ftp (with 100-110MB/s read and 60MB/s write), the read speed uses few % of CPU and the write speed also saturates the CPU with proftpd and raid5 processes.
