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...
Hmm, I'm not seeing the performance that some of you guys are on our ReadyNAs Business 6TB unit.
ReadyNAS PRO side:
- 3GB RAM
- Bog standard 6x 1TB drives - XRAID
- No journaling
- Paired gigabit ethernet
Server side:
- Supermicro server
- SATA HDD
- Single gigabit ethernet
- 2GB RAM
Switch:
HP Procurve gigabit switch
No jumbo frames enabled
CAT5e throughout...
When running a ReadyNAS backup copying from the server to the ReadyNAS over CIF I'm only seeing a 25% network utilisation (but rock solid 25%), which is odd. I haven't had time to look into why this is so low, but the Procurve isn't doing much, I'm not getting any errors, no high CPU utilisation and I'm assuming the source 'server side' SATA drive can rummage up data quicker than ~30MB/s.
The 25% utilisation is confirmed in both the Windows GUI and the Procurve port utilisation screen.
Data being copied is a bunch of installation files for a variety of applications of random sizes. i.e. some 700MB ZIP files, some 30MB installers...
Any ideas?
UPDATE: Doh, this does seem to be the SATA drive maxing out. I just copied another data stream from a second drive on the same server and network utilisation went up to 50%... i.e. 62MB/s...
It does seem a little odd that when copying from a single server source it seems to max out around 40% utilisation, i.e. 50MB/s though, unless I'm now maxing out 4x 10k rpm SAS drives in RAID5!
