+## Performance
 
 * Typically it parses one mp3-file with size around 6-7 mb in less than 0.001 sec.
 * List of 112 files with constant & variable bitRate with total duration 5:22:28 are parsed in 1.76 sec. *getId3* library against exactly the same mp3 list works for 8x-10x slower - 9.9 sec.
 * If you want, there's a very easy way to compare. Just install `nass600/get-id3` package and run console scanner against any folder with audios. It will print time that Mp3Info spent and that getId3.

+## Console scanner
 To test Mp3Info you can use built-in script that scans dirs and analyzes all mp3-files inside them. To launch script against current folder:
 
 ```bash
 php bin/scan ./
 ```
