Hi

On our SQl Server (2000) we can have queries that take at least 10-20mins
(require full table scan fo billion row table). When one of these queries
is running it substantailly slows down very quick queries (sub second
queries take several seconds).

I believe there is no way to set priorities but was wondering if there
are other configuration settings that could help. The server is dual
processor so maybe setting maxdop to 1 will help. Memory size is
dynmaically assigned up to 4Gb but as the DB size is > 1Tb I'm not sure
if allowing this much memory is actually decreasing performance when the
quick query trys to get through.

Any suggestions.

Thanks
Mike
