Below are some [benchmarks](bench) comparing the time needed to log 1,000,000 lines to file under Ubuntu 64 bit, Intel i7-4770 CPU @ 3.40GHz (the best of 3 runs for each logger):
|threads|boost log|glog|g2log <sup>async mode</sup>|spdlog|spdlog <sup>async mode</sup>|
|-------|:-------:|:-----:|------:|------:|------:|
