I'm investigating a performance problem with the TRANSUM dissector. I'd like to measure the accumulated time taken to execute a function in a Release build. My basic idea is to do something like this: guint32 execute_time_us; . . start_stopwatch(&execute_time_us); function_call_to_be_measured(); pause_stopwatch(&execute_time_us); . . . stop_and_output_stopwatch(&execute_time_us); Is there a standard way to do this in Wireshark? How can I output the accumulated time on, say, the Status Line?
Not sure about the Status line question, but you can measure elapsed microseconds with something like: guint64 start_time, end_time; start_time = g_get_monotonic_time(); // ... end_time = g_get_monotonic_time(); // ... g_print("elapsed us: %" G_GUINT64_FORMAT, end_time - start_time); https://developer.gnome.org/glib/stable/glib-Date-and-Time-Functions.html#g-get-monotonic-time -- Kind regards, Peter Wu https://lekensteyn.nl ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
