Here's some benchmarks showing the effects of interrupt distribution on
a T2. The test was done with iperf using a pair of T5220 boxes, each with
a 10GBe NIU (XAUI) connected back to back. The kernel version is
2.6.30-rc5.
TCP | Stock Linear RR IRQ Optimized IRQ
Streams | 2.6.30-rc5 Distribution Distribution
| Gbits/sec Gbits/sec Gbits/sec
