Thanks. Now about 2 core vs 4 core Woodcrest. For HP DL360 I see similarly priced dual core 5160@3GHz and four core E5320@1.86Ghz. According to article's scaling data PostgreSQL performance should be similar (1.86GHz * 2 * 80% = ~3GHz). And quad core has slightly slower FSB (1066 vs 1333). So it looks like more likely dual core 5160 Woodrest is the way to go if I want "ultimate" performance on two sockets? Besides that I think it should consume a bit less power!? Mindaugas
