Currently this project tests the following libraries:
Benchmarking rule set:
- logging message in google logging prefix format (
\[IWEF\]yyyymmdd hh:mm:ss.uuuuuu threadid file:line\] msg) - single-thread
- multi-thread
- async logging
- formatted (or placeholder) log message
Notes:
- The glog does not support single-thread and async logging
- APIs for formatting log messages differ between libraries
Run on macOS:
