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