As I said - I'm using sql server standard .. asynchronous mirroring is not avialable in that edition I believe (correct me if I'm wrong).
Can you clarify
Another angle is to look at the context of these INSERT statements. I guess since they are problematic, that you are not submitting these in singletons a few times a day, but maybe you are inserting many rows at a time? In such, there is plenty of oppurtunities for improvement!
I think you may have missed a few words so I am unsure what you mean:-)
