On a related note, what's the consensus on enabling hyperthreading on a CentOS system? Good, bad, indifferent? The systems will be used as developer workstations.

If it is a 100% workstation only (no mysql, postgres etc), then it is ok to use it. Otherwise, you are asking for trouble.

Any comments on this?

I have a x86-64 system with one Xeon(TM) CPU 3.00GHz running CentOS 4 with 2.6.9-34.0.1.ELsmp (hyperthreading) as a production PostgreSQL 8.x database. No probs so far.

Regards,

I run a dual xeon machine with HT enabled, and see no issues. Good machine.
