- On a single file basis, SHRI compresses more than LZX. LZX is only superior

- Building LZX archives with no compression (to group similar files together)
- and _then_ compressing them with SHRI almost always results in a win over
- using LZX alone or LHA + xpk. Wasn't it you yourself who wrote an LHA+xpk
- archiving script which did this?
-
- And I know SHRI is slow - if I'm going to use it, I'll leave it running in the
- background and no longer have to worry about it.
-
- BTW, if you want a REALLY slow compression algorithm, which as a sideline
- consumes huge amounts of memory, try xpkDMCB...
