samplingRate

Controls the sampling interval in bytes. The lower the interval, the more precise the profile is. However it comes at the cost of performance. Default is 100000 (100KB). That is enough to observe allocation sites that make allocations >500KB total, where total equals to a single allocation size times the number of such allocations at the same call site. Equivalent to --memlog-sampling-rate in Chrome. Must be an integer between 1000 and 10000000.
