So try to have a look in the logs (generally this should be in

So far (check today's archives) not at all. We will have to wait to see
what develops.
I understand and it's actually the original way I was designing the
databases. Only thing that stopped me from doing it that way was the fact
that the sets a user belongs to (vsets) is also dynamic, the user can change
which sets he/she belongs to. Meaning that if there are 50 sets and 50

Not sure but given that you suffer from non-linear degradation in

too frequently during the batch load process. Check the

b. load the various bulks
c. after loading, define Email, eg. as (unique)
