Hi, The FreeBSD 6.0 SMP Kernel recognizes my two XEONS as 4 CPUs. A single postgresql query, as I could see in the top utility, can use a maximum of 25% of CPU time, since it runs on one single virtual CPU, which means for me "half of a XEON". Is that correct? If yes, is there a way to change that, and accelerate long queries (which are all CPU-bound) in giving them more processing time, like a full XEON? Both XEONS? Should I disable Hyperthreading for that?
