In reply to:

It was mentioned that there's a performance hit using the developer version of the kernel, my question is, how much of a perf. hit?

Not much.. The bootup takes a few seconds longer (not really noticible..)The disk caching doesn't have as much memory to deal with though - so the hard drives stay spun-up longer then w/ the consumer release...
