Does Atom dual-core work with SMP?

2009-11-23 Thread Douglas Maus
Does anyone have experience whether dual core actually gets better OpenBSD SMP performance between the Intel Atom 230 (single core) and Atom 330 (dual core)? (such as between the Supermicro SYS-5015A-L and Supermicro SYS-5015A-H) Is the Atom 330 worth the extra bucks? Thanks for any insight.

As a rule of dumb, and as far as the big lock is present -OpenBSD has not the best performance-wise SMP solution out there-, if your dealing with high I/O rates -all computing at kernel space-, a dual core system isn't going to scale very well... So you will get similar performance on both
