I guess that depends on how you define "performance".
The MAX_INTS setting in the em driver essentially does what polling does (in reducing interrupts) without the overhead. So there is really no way that polling could be better. With polling you have a lot of unnecessary overhead. Setting MAX_INTS properly has zero overhead for the O/S

Polling is simply unecessary in most cases. You could get better performance using an em driver and setting max ints to whatever is optimal for your system. Polling adds latency and over head for no good reason.
Polling often provides better performance, at the expense of higher overhead.
