AFAIK the "old" profiler is a statistic profiler, i.e.: at certain
points in time it looks which function is running. Every time you run a
profile, this can be different functions. If you want a more precise
profile, just let it run for a longer amount of time (i.e.: send more
than one file, or send a larger file).
