>
> Hi,
>
> I had noticed that one of our triggers is performing very
> badly. I had disabled the trigger to test replication and
> there was a issue with the trigger. When the developer
> changed the trigger and enabled it, replication slowed down
> to one record per second (other tables are being updated,
> instered, and deleted from).
>
> I analyzed the plans for all sql statements generated
> in the trigger itself and they are all using the correct
> indices etc. There are no full table scans etc. We have
> simliar trigger on our other replicated tables that are not
> seeing THIS bad performance.
>
> Any one have any suggestions/links for putting this
> trigger through the paces to determine the bottleneck?
>
> Thanks,
>
