It does have many nice extra options (such as the multi-volume packed file).
However, it is not faster than LHA 2.1x.  It's about half the speed.  It is
faster than LHA 2.1x if you use less compression, but then it is slower than
ZIP and doesn't compress as well.

It compresses better than PKZIP, but LHA 2.1x beats it on about 9 out of 10
files.  Regardless, the results of the two are very close.
