Re: updated Delphi FastZlib 1.2.3
Jedivcs is actually using (mostly) abbrevia for un-/compression
and I wanted to know if it could profit by using another
So I compiled a comparision pdf which is available in the
jedi newsgroup: forums.talkto.net:jedi.binaries
It shows how the libraries compress and uncompress several
text files and actually compares abbrevia, uiUcl, FastLib and
a bzip2 library.
Compress ration: nearly as good as bzip2
Compress performance: 1st place
Uncompress performance: 1st place
really impressing, keep your good work!
Just curious if c sources are ready for *nix OS?

- Re: PDS Compress
... The compress typically takes much longer than than the user expects -- especially if the system is heavily loaded -- and sooner or later someone will attention-out with PA1 in the middle of a big compress or have someone else cancel their session, either of which is guaranteed to trash the PDS and get all sorts of unpredictable strangeness. ... If you allow such compresses, you need at the very least to train users to know that interrupting a PDS compress process with PA1 or having their session cancelled during a compress will trash the PDS, to call if they think they are hung and allow tech support to determine if they are really hung or still running the compress, and use HSM or some other means to auto back up such libraries when changed so when they do get trashed they are easier to restore and it's simpler to determine what recent updates have been lost. ...
