Home -> Community -> Mailing Lists -> Oracle-L -> Running/Licensing Hyperthreaded Intel Pentium4 Xeon CPU's on Linu
OK, I've got this new Dell Linux server with 4 "Hyperthreaded" Pentium4 Xeon
CPU's. There are 4 physical CPU's but with hyperthreading the O/S sees 8
CPU's as is reported in top. I've installed Oracle on this machine and it
seems to run as if there really were 8 CPU's. Could that be true? Is there a
performance gain for Oracle? --As if I really did have 8 CPU's? How does
this work? For init.ora tuning parameters should I count the 4 physical
CPU's or the 8 virtual CPU's? Any reports on running Oracle/Linux on these
hyperthreaded Pentium4 Xeon CPU's?
I'm afraid to ask Oracle about the licensing since they always answer with the higher number. ;-)
