Hi Radu, Making stats dynamic would have a perf cost. That was the reason it was introduced as a compile time option. Why do we need it changed? Also, it looks like this patch is only disabling stats printing when timeout is 0. I don't see stats collection being conditional. Stats collection would also have perf impact, right?

I don't see stats collection being conditional. Stats collection would also have perf impact, right? I don't think there is a measurable performance impact because these are per burst calls.
