The
DTTrigProd::beginRun()uses 7.3 MB memory per stream (1 thread/stream profile vs 4 thread/stream profile. For an 8-thread/stream PromptReco this would correspond to 58 MB in total.Does all of it need to be replicated among streams? Are the "TU"s being modified during the event processing?
Avoiding the replication could save 51 MB memory in PromptReco
