Xen Performance

Performance measurements were not part of the original test plan, but some performance measurements have been capture to establish a baseline of expected performance.

Test Methodology

Test Characteristics:

  • All VMs at one site are on the same VM server, all VMs are exclusive.
  • All results are captured for default bandwidth allocation (100Mb/s shaped), unless otherwise stated.
  • All results are captured for default OS (OpenVZ=Fedora 15 STD and Xen= Ubuntu 12).
  • All results collected between 2013-08-16.

Iperf TCP measurements captured in this page have the following assumptions:

  • All results are for a 60 second test run.
  • iperf '1 client' scenario command: 'iperf -c dest_host -t 60'
  • iperf '5 clients' scenario command: 'iperf -c dest_host -t 60 -P 5'
  • iperf '10 clients' scenario command: 'iperf -c dest_host -t 60 -P 10'

Iperf UDP measurements captured in this page have the following assumptions:

  • Each test run is 60 seconds.
  • UDP measurements within a rack requested a bandwidth of 1Gbits/sec for test run
