I just retried the following code that you specified and got 0.00348563 which is about 10 times more time than you take.
are you sure you are getting 0.000369282 ? My processor speed is about 800 mHz and I am running linux - ubuntu. thanks Strange. I got on my 3 years old Fujitsu S series lifebook 0.000369232. It has a slow processor and 1 GB RAM.
