4 1/2 seconds for a count(*) ? This seems a bit rough - is there anything else I can try to optimize my Database? You can imagine that slightly more complex queries goes out the roof.

Well a couple of things.

1. You put all your money in the wrong place.. 1 hard drive!!??!!
Yes, I realize 1 hard drive could cause a bottle neck, but on average I'm sitting on a 1-2% wait for IO.
2. What is your maintenance regimen? Vacuum, Analyze????
I'm doing a daily VACUUM ANALYZE, but just to be on the safe side, I performed one manually before I ran my test, thinking that I might have to up the frequency.
