## Benchmarks
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):
Below are some [benchmarks](bench) comparing popular log libraries under Ubuntu 64 bit, Intel i7-4770 CPU @ 3.40GHz
#### Synchronous mode
Time needed to log 1,000,000 lines under synchronous mode (in seconds, the best of 3 runs):

### ASynchronous mode
#### Asynchronous mode
Time needed to log 1,000,000 lines under asynchronous mode, i.e. the time it takes to put them in the async queue (in seconds, the best of 3 runs):
