In normal circumstances does locking a table in access exclusive mode improve insert, update and delete operation performance on that table.
Is MVCC disabled or somehow has less work to do?
Cheers
Jeremy

MVCC certainly isn't disabled. Does it have less work to do? That's a
bit harder to say but my guess is "not so much that you'd actually be
able to notice it."..
Thanks,
Stephen
