Hi David,

I've no expirience with MM, but a bit in perf optimizing.

It could be some code calling requeries recursively:
that would really hurt if many views are open.

I'ld suggest running the fast and the slow operation
under the coverage profiler.

In the analysis DON'T go
for the timings via GUI at first,
but do a bit of sql-slight-of-hand
to count the functioncalls and
timings of both measurements.

For me that often shows the critical section.
