Thanks for the advice. Unfortunately I need to do a large number of writes. I have in effect, a batch process to run a couple of times a day. I think some profiling and some proof-of-concept tests might be a good idea, or i'll run out of free CPU cycles ;)
I'll post a follow up if I get a chance. So much to do and so little time ;) Cheers On Sep 5, 1:50 am, Bill <[EMAIL PROTECTED]> wrote: > The small amount of benchmarks I've run show puts to be very > expensive, so minimizing them in general will help.
