I've been playing catch up in the archives here, and I thought I might 
weigh in with my motherboard latency results.

This is a motherboard that I initially tried a latency test when I 
bought it, and it was very disappointing.  However, my reading gave me a 
few configuration tweaks that I had not previously tried.

In the UEFI:
- disable c6 state
- disable 'cool-n-quiet'
- no overclocking, 'auto' on cpu and memory speed

The hardware:
Asus E35M1-M Pro motherboard, with E-350 APU @ 1.6GHz
4GB DDR3 1066 RAM

I used the Ubuntu 10.04 LTS install I had in my other computer, booting 
with "isol_cpus" enabled.  I simply unplugged the drive and moved it over.

The latency results, performed while doing simultaneous full-screen 
glxgears and `find /`:
servo thread (1ms)    6684ns
base thread (25us)    4288ns
