benchmarking: results from Xbench

Post by grahamperrin » Fri Nov 09, 2012 2:23 am

This topic, for anyone who'd like to share results from Xbench 1.3 (1.3) or greater.

(In separate topics: results from Bonnie++, from IOzone, from others …)

My Xbench can't connect to the Xbench server:

In the meantime, someone else's results appear under Rapidly deteriorating performance

System Info
Xbench Version 1.3
System Version 10.8.2 (12C60)
Physical RAM 4096 MB
Model MacPro3,1
Drive Type Zdata
Disk Test 31.02
Sequential 141.81
**Uncached Write 108.27 66.47 MB/sec [4K blocks]
Uncached Write 55.09 31.17 MB/sec [256K blocks]
**Uncached Read 1419.22 415.34 MB/sec [4K blocks]
** Uncached Read 8805.55 4425.60 MB/sec [256K blocks]
Random 17.41
**Uncached Write 4.55 0.48 MB/sec [4K blocks]
Uncached Write 107.50 34.42 MB/sec [256K blocks]
Uncached Read 1367.43 9.69 MB/sec [4K blocks]
**Uncached Read 23770.35 4410.76 MB/sec [256K blocks]

** These speeds don't look like they could be true for *uncached* operation. The HD is connected on a USB 2 interface. I'd really love to have 4425.60 MB/sec :-) - Xbench gave me a similar result when connecting this drive to a firewire 800 port.

result for dataset gjp22, CoreStorage and JHFS+ in the mix

Post by grahamperrin » Fri Nov 09, 2012 6:52 am

Tested: dataset gjp22

As the disk for this pool is shared with a JHFS+ startup volume, so I do not expect great performance.

Plus there's a combination of two pool technologies (ZFS slice is part of a CoreStorage LV), effects of which on performance are unknown.
