In Response To: RE: RE: IDS 7.31 Solaris8 - Long Checkpoints (Norma Jean Sebastian)

No NJ, that would be changing too many things at once. Even Art has too
many. For starters just change what I said, bounce you engine, and see what
your results are.
Changing buffers often causes a retune of the whole environment. I agree he
could be using many more, but lets focus on the current problem first.
Thanks!
