That's interesting, I didn't know that. Any idea how much of a performance
drag we're talking about?

Those links are great!!! Thank you for bringing them to my attantion. And a
BIG thank you to the authors (Josh Berkus & Shridhar Daithankar) for making
this available. I've been looking for an authoritative and comprehensive
source for performance tuning tips but haven't found much except for little
tidbits here and there. This is very nice.

Don't know much about Debian, but we've been working with RH for years. I've
had nothing but good experiences with them. (Except maybe for RH8) The new
Enterprise direction they're going in is exectly what we need. Longer
testing cycles and better tuned distributions are good for businesses like
us. We don't necessarily need the latest and greates we need the latest and
most stable to guarantee the highest return on our investment. But, this
discussion is for another list... :)
Thanks for your advice. This list has proved to be a great asset so far.
