LZIP FOR WINDOWS SOFTWARE

As separate projects, why does the plzip team demand lzip source must exist to make the plzip software? Separate means each should stand alone supplying what it needs.

LZIP FOR WINDOWS SOFTWARE

The lzip software came from the Fedora repo. But lzip and plzip are two distinct source projects. Probably lzlib.h is included with lzip‘s source code. Trying to make it reported the following: $ makeĬ:33:10: fatal error: lzlib.h: No such file or directory Extract from tarfile, which creates a subdirectory and puts everything in it.Building such applications is not typically difficult. It requires downloading - its v1.8 compressed tarfile is only 55K - and building. Plzip is not included in the Fedora repository. It does not come with an unlzip, so use the lzip -d option. As with most other compressors, using -6 gives the default compression and -9 gives the best compression. Decompressing uses the -d option or run unpigz.

Pigz is a parallel implementation of gzip.

But it can’t hurt to look now at these other four compressors - pigz, lzip, plzip, and pixz - with one rerun of zstd/pzstd needed for comparison. In my earlier article I had no intention to hunt down all possible compressors.

Again, zstd/pzstd did well with compression ratios with excellent times.

While xz had greater compression ratios its times were terrible.

Instead, zstd/pzstd did well on compression ratio and blew all others out on time.

Although running xz on my Installdir data got a slightly smaller size, its times were horrible.

One commenter pointed to a thorough article identifying why xz is a poor compressor to use. My notes about this appear at the end of the earlier article’s Results Tables section. Its man page specifies -T0 uses as many threads as the system cores. Regarding using xz -T to specify the threads, I tried its -T0 option. Since my file compressors article some suggestions asked for more testing using pigz, lzip, plzip, pixz, and running xz with its -T option.
