[SPAM] AW: [Xen-users] GPLPV benchmark results

["Steffen Heil" <lists@xxxxxxxxxxxxxxx>]

Hi

There is something wrong with your system. Not getting above 1.8 MB/s is not
okay.
I attached a graph of PassMark on my system, reaching 40.8 MB/s...
Note that this speed is reached WITHOUT PV drivers. I assume the PV drivers
would be even faster, but the net device does not work form e.

Regards,
  Steffen

Hi James,

I tested (as I wrote a few days ago) the latest PV drivers release, and they
seem to work correctly apart of the "Safely remove Xen Net Device Driver"
tray
icon glitch.

I made a series of benchmarks with PassMark's PerformanceTest on 6 twin
concurrent VMs with the PV drivers installed, both with the /GPLPV switch on
and off, and on one lonely VM, still in both situations.

I tested in particular the disk performance and I noticed a decrease of I/O
throughput, while at the same time a significant decrease of the VM CPU
utilization.

The test results can be downloaded from:

Best Regards,
Sandro
