We are replacing a box that is fairly busy with many different processes
(sendmail / pop3). The new MB and CPU is hyperthreading capable. Is it
worth it to enable this ? Does anyone have any real world experiences with
it in RELENG_4 that say one way or the other to use or not use it ?
dmesg shows,
CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (2992.52-MHz 686-class CPU)
