Burst Report Performance

[cognosMX]

There is a report using the burst feature. The report is sent to more than 100 mail addresses with the help of bursting feature. Cognos runs the report repeatedly for each burst process. Because of running reports repeatedly, our other reports are stuck in the pending statu. How can Bursting report be delivered faster? Is it possible to work once and distribute cognos to mail groups on itself? We use Cognos 10.2.2.

Cognos can do the bursting report in this way?
Cognos run the report once and after cognos will parse it distributes to mail groups.
