ID3 Tags require a read operation in order to work, 128 bytes for ID3v1 and alot more for ID3v2. This means you have to open a remote file handle, perform a file seek to the end of the file, and read in 128 bytes for each file, that's 220*128 in your case or ~25600bytes, altho it doesn't seem like alot, the process of opening a file handle is not that fast either. You can try this in windows explorer, by right clicking the columns and display the artist tag for your mp3's, it takes a couple seconds even on windows.
It might be good for XBMP to implement some type of ID3 caching system, but I'm not doing any of their development, so that's just a suggestion.
So just disable ID3 for now, unless you just have a small amount of files, it will take this long. It's not a problem with the program just user misunderstanding.
