how obscene is 1500 records in memory? on a 3ghz machine with 1gb of
ram thats like wondering if your wallet will miss 5 cents.<br>
<br>
I'll happily cache 100000 records in memory, as long as its updated
properly, and do my seeks un 300ms on that kind of search. RAM is no
magical wonderbeing. the purpose of increasing ram is so that you can
use it for such things,<br>
