# Performance
* It parses a bunch of mp3 files in less than a half of second (without tags).
* It parses a bunch of mp3 files with their tags in two seconds or less (with both id3v1 and id3v2).
A bunch - **878 megabytes** of mp3 files (**33 tracks** with a total length **8:37:42**).
* Typically it parses one mp3-file with size around 6-7 mb in less that 0.001 sec.
* Few files constant & variable bitRate with total duration 5:22:28 are parsed in 1.76 sec.
# 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:
