dumpInterval number (optional) - The interval in milliseconds at
which samples are written to the trace. Each write is a full snapshot of
every sampled allocation that is still live, so short intervals can fill the
trace buffer quickly in long recordings. Defaults to 0, which writes a
single snapshot when tracing stops.
samplingInterval number (optional) - The average number of bytes
allocated between samples. Lower values give a more precise profile at a
higher performance cost. Must be greater than 0. Defaults to Chromium's
default, currently 131072 (128 KiB).
