Your speed results are about what I would expect. LHarc is slow. However
I think your old version is doing a poor job of compressing compared to
v1.x. Also you are comparing an archive with a compressed file, a
procedure which counts the header information against the archiver. For
image data I would expect the compressor only code from lharc, known as
freeze, to produce an output which is about 10-15% smaller than compress
on images, up to 40% smaller for some text files.

For very large images the 'compact' compressor does a good job, and it
is most definitely faster than compress.
