The VolanoMark 10/100 loopback test was ran to compare the 2.4.4 and 2.4.4+MQ Scheduler kernels.
More information on the MQ scheduler can be found at http://lse.sourceforge.net/scheduling/
The MQ Scheduler patch improved message throughput considerably.
On a 8P system, message throughput increased by 147 % from 18,678
msg/s to 46,167 msg/s.
On a 4P system, message throughput increased by 32 % from
22,331 msg/s to 29,440 msg/s.
The throughput from 4P to 8P no longer scales negatively.
