Well, what it's doing in the background just sitting there at a prompt overnight I can't really say... maybe it's inclined to do stuff like this...


I'm guessing you're not running on linux, since you mentioned coldfusion :)
Sounds like the "residual" system load was higher than during normal mySQL usage; if you do happen to be on linux check out vmstat.


Yes - Linux (slackware). Will take a look at vmstat - thanks.


How big is the DB? Can it fit in memory? (make sure you have good UPS if so!)

DB isn't terribly large - I don't have the #'s handy though...


In regards, to the subject line, I also wanted to round this discussion out by daying, "NO", IMO :) MySQL has been improving over the years in terms of its own efficiency, and the bottom line is that CPU time is continually cheaper ;)

Okay...

Matt
