Sample trace: https://ui.perfetto.dev/#!/?s=33fa111ddc4df0e7fc6ee0ad39010663e3ffed3ad4f09345e6a54a8fdc467

The executeCommand there is ps -A | grep, which is extremely slow. Sample trace using pgrep instead (which is available back to API 23): https://ui.perfetto.dev/#!/?s=33fa111ddc4df0e7fc6ee0ad39010663e3ffed3ad4f09345e6a54a8fdc467
