A decent chunk of the logcat profile is spent formatting the timestamps for each line, and most of that time was going to snprintf(3). We should find all the places that could benefit from a lighter-weight "format an integer" and share something between them, but this is easy for now. Before: ----------------------------------------------------------- Benchmark Time CPU Iterations ----------------------------------------------------------- BM_time_strftime 781 ns 775 ns 893102 After: ----------------------------------------------------------- Benchmark Time CPU Iterations ----------------------------------------------------------- BM_time_strftime 149 ns 147 ns 4750782 Much of the remaining time is in tzset() which seems unfortunate.
