Re: intel vs amd benchmark for pg server

1. 64MB machines beat 192MB and 240MB machies.

2. On 64 MB machine I tested on 5400rpm drive
and still much faster than athlon machine.

3. On sis machine I am using a separete ati agp card
not the built in one and as a result
i am using all memory.

You would expect AMD machines to be at least
slightly faster because cpu speed ratio are
about 2 or bigger. You might not expect
linear scaling but at least faster you know.

Also as I said kernel compilation time
scales almost linearly with cpu speed
