Word description Formats and prints a profile report generated by top-down, top-down-max-depth, cross-section, or flat. Threads and sibling calls are sorted by decreasing running time. The time % column shows each row's share of the total sampled time across all threads. The GC, JIT, FFI and FT percentages are relative to that row's running time. Inclusive call times overlap, so percentages should not be summed across callstack levels.
