Yes, I think that EXCL would make a huge difference.

And if it is EXCL then there would be no need for buffering (unless, as I think I read, there is TRANSACTION involved) because Windows itself would cache the updates until it *had to* frre up more cache space.

It also wasn't clear if the TABLEUPDATE() is done once per mass change or on every record updated. There could be time to be saved there too.
