It still sucks quite a bit of CPU, either way, although top could be misleading me. Still, if we're going to be comparing with results from Linux which are near the peak of it's performance curve we don't want to be running in the middle of our much lower one. > > sucking down millions of records > > Millions eh? What's 30x10000? Right; I was somehow under the impression it was selecting multiple records; I associated the relatively high CPU usage from super-smack with fetching the result set, when really it's got plenty to do just sending queries. > No more help from you please. No, at least not late at night after not having a caffeine fix for about 8 hours.
