Ali,

I think the best that could be done is let the engine finish each task
as fast as it can.

A low-priority task, could hold resources needed by a high priority
(since update critical regions of the database) and the low priority
being slow will slow down the hight priority too.

Another thing to consider, FB in the current state are sometimes CPU
bound, with you use CPU to slow downa low priority you will in fact slow
down the whole system.

I am sure the gurus will correct me if I am wrong in those statements.

see you !
