I am about to compile an optimized Kernel for my new servers.  I'm used to
compiling kernels but not for this specification of machine - these
servers are all Dual P4-Xeon 2.2GHz (512Kb cache) using Intel E7500
(Plumas) chipsets, ECC DDR RAM..  

- which processor type to select - I assume Pentium-4 since no Xeon
option.

- how much High Memory Support - some of these servers have 2GB, some 1GB
RAM.  I don't foresee expanding the RAM beyond 4GB in the future.

- what to set for User address space size - why?

Finally.  Some of these servers will be high-throughput number crunchers
and I have been advised by the software vendor to switch off
hyper-threading in the BIOS (which I have done) as their tests indicate it
degrades compute intensive tasks.  But one server will be a general
purpose machine and from Intel's pages it sounds like hyper-threading
would be good for this.  Anyone have experience with this?  Are there any
Linux specific optimizations?

TIA
