Aha!! We changed the page size to 150 last night, and this morning (it's the busiest at the start of the day, and their slowest period) the speed was fine!

NOW, they tell me: "And the paged memory is much less as well"

So it WAS using a lot of memory!

For lack of a more scientific method, they are now going to play around with various methods between 75 and 150, to see which is going to be optimal for them

Thanks for all the help!
