'''Performance tests and results'''

----

Before performing benchmarks - configure [[WindowsGuestDrivers/kvmnet/registry|Windows parameters]]

= Tests =
== Tools used for performance tests ==
=== iperf ===
* [http://www.noc.ucf.edu/Tools/Iperf/ Download]
* Typical command line: iperf -c <IP> -w <TCP window size>
* Pros: ability to control the TCP window size from command line and intermidiate results printouts during the test.
* Cons: High CPU consumption on Linux machines.

=== netperf ===
* [http://www.netperf.org/netperf/DownloadNetperf.html Download]
* Typical command line: netperf -H <IP> -l <test length> -- -m <message size>
* Cons: No control over TCP windows. Windows version doesn't have some of the Linux version feature. Windows server should be restarted after each test.

==== Additional scripts ====
* netkvm\tests\netperf_wrapper.rb - the scrip will run netperf according to its configuration (by default running 3 times for each message size and iterating message sizes between 32byte to 16K).
* netkvm\tests\netperf_log_parser.rb - parsing raw netperf output

=== NTttcp ===
* [http://www.microsoft.com/whdc/device/network/TCP_tool.mspx How to Use NTttcp to Test Network Performance]
* Cons: Windows only tool
