Optimized Linux 2.6.10 Kernel for Dual Xeon with Hyperthreading
Anyone have tips on configuring the 2.6.10 kernel to take full advantage of dual 2.4 Ghz Xeons?
I'm not getting expected benchmark results.... and seemingly was better off with a single 2600+ AMD processor.

amdtemp
AMDTEMP(4) BSD Kernel Interfaces Manual AMDTEMP(4)
NAME
amdtemp -- AMD CPU on-die digital thermal sensor
SYNOPSIS
amdtemp* at pchb?
DESCRIPTION
The amdtemp driver provides support for the on-die digital thermal sensor present on AMD K8, AMD Barcelona, AMD Phenom, AMD Griffin, and AMD
Fusion CPUs.
These sensors were officially introduced in AMD K8 Revision F processors, and provide 0.5 degC accuracy. Precision was improved in Revision
G chips, which provide two more bits for 0.25 degC steppings. Each core has two temperature sensors, and there are up to two cores per CPU
socket.
AMD Barcelona, AMD Phenom, AMD Griffin, and AMD Fusion provide 0.125 degC accuracy and provide one temperature sensor for each CPU socket.
The amdtemp driver reports temperatures through the envsys(4) API.
Sensor Units Typical Use
CPUN sensor0 uK cpuN temperature
SEE ALSO
envsys(4), envstat(8), powerd(8)
HISTORY
The amdtemp driver first appeared in OpenBSD 4.4 named ``kate''. It was then ported to NetBSD 5.0. The driver has been renamed with support
for newer AMD CPUs.
AUTHORS
The amdtemp driver was written by Constantine A. Murenin <cnst@openbsd.org> whilst at the University of Waterloo. It was adapted to NetBSD
by Christoph Egger.
