tux3-2.6.8.1-A5 performance

[Yaoping Ruan]

Hi Ingo:

I did see significant performance improvement of 2.6.9-rc3. But, -A6
still got lower throughput than the user space server (Flash). Here's
the numbers:

In-memory workload, 1024 concurrent connections, on 1 processor Xeon
3.06GHz:

Tux: 1746 Mb/s  (was 1323 Mb/s on 2.6.8.1, 32% improvement)
Flash: 2134 Mb/s (was 1630 Mb/s on 2.6.8.1, 31% improvement)

This morning when I came in, I measured throughput on 2 processors:

Tux: 2408 Mb/s (was 1803 Mb/s on 2.6.8.1, 34% improvement)
Flash: 3137 Mb/s (was 2331 Mb/s on 2.6.8.1, 35% improvement)

Wondering if RH Enterprise release would do any better?
