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...
After some frustration with a new Ultra 4 (populated with 4 x HITACHI Deskstar 7K2000 HDS722020ALA330 (0F10311) 2TB 7200 RPM drives in X-RAID2) getting a paltry 6-7 MBps read speed from a newly built Windows 7 64-bit rig, I did some research and found I could run jumbo frames on my Trendnet router (TEW-633GR). Before that I tried TCP Optimizer (ended up resetting to Windows defaults), then using the Vista/Win7 tweaks from SpeedGuide.net (kept most of those), disabled flow control on the Realtek 8111E onboard NIC (briefly got 100 MBps on a large transfer! ... but it didn't hold after a reboot :( reset it to Enabled, as there were a lot of network errors produced, even though the copied file, copied back, passed a checksum matching test with the original file) ... I finally got smart and updated the Realtek's driver and enabled jumbo frames on all NICs attached to the HP Procurve 1800-8 G switch, enabling switch-wide JFs on that.
I then did a drag-and-drop copy test of a 9 GB file from the Ultra 4 to the Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM SATA 3 system drive.... over 100 MBps!!! :shock: I was stunned. Repeated that test several times after a few reboots. Pure gold. A driver update + JFs enabled on an old D-Link DGE-530T on an XP Pro SP3 box also resulted in increased read speeds from the Ultra 4 (in the low 30s MBps). Similarly my original Infrant (remember THEM!!! ;-) ) ReadyNAS (Sparc-powered 256 MB of RAM little beast :-) ) also benefited from JFs being enabled. But the Ultra 4 + new Win 7 rig combo was my main concern.
I was really worried about that nice Procurve switch, but it's a rock, so I wasn't willing to throw it under the bus.
As far as the Vista/Win7 tweakable parameters go, you just gotta play with them, but the SpeedGuide.net page is a gem.
re: IOMeter, I messed around with it a bit on the XP box, but for my purposes the practical drag-and-drop tests were sufficient indicators that the problem had been well and truly licked. I'd be happy to drag IOMeter out and run it on both PCs and post results, but someone smarter than me is going to have to tell me how to get meaningful results. For example, after opening the .icf file provided by Infr-- errrrr, Netgear, and running the tests, there was nothing listed for Read Speed in MBps. The Write test seemed to indicate 44/45 MBps, and that seems about right. Didn't have time to mess around with it further.
Anyway, hope these anecdotal data will help someone or provide encouragement to tinker.
Cheers.
I should add that this is with CIFS and HTTP/S the only enabled services, and that the Ultra 4 and the original ReadyNAS are running the current RAIDiators for each model.
