Heap profiling sampling interval (in bytes).
Heap profiling service uses Poisson process to sample allocations. Default value for the interval between samples is 100000 (100KB).

Lower intervals produce higher samples resolution, but come at a cost of higher performance overhead. – Mac, Windows, Linux, Chrome OS, Android

#memlog-sampling-rate
