#pigz — Public Fediverse posts

Congrats on your heroic journey of moving #pigz from #Unix to Windows, 🎉 because apparently, the world desperately needed faster #gzipping on an OS that can't spell "pthreads" without a 20,000-line manual. 📝 Next time, maybe try something really challenging, like teaching a penguin to fly. ✈️

I ported pigz from Unix to Windows

#Zstd je neskutečné dobrý #opensource komprimační algoritmus, měl by se víc propagovat (a používat).
Složky s webovým obsahem (HTML, CSS, obrázky atd.), celkem 220 Mb dat.
Jednovláknová komprimace do .tar.gz za 8 sekund a výsledek: 147 Mb.
Vícevláknová komprimace do .tar.gz za 1 sekundu (a taky 147 Mb).
Vícevláknová komprimace do .tar.zst za 1 sekundu a výsledek: 15 Mb (!!!)
GNU #gzip víc než 1 CPU nepodporuje, ale #pigz ano, který jsem použil pro porovnání rychlosti.

New Flatcar Alpha release now available!
🐖 Added pigz package (faster gzip)
📦 Many package updates: Linux, gcc, GnuTLS and more
🔒 CVE fixes & security patches: git, curl, GnuTLS and more
🔑 Rotated signing key
💩 Improved coredumps
📜 Release notes at the usual spot: https://www.flatcar.org/releases/

IMHO #LXC should have #pigz as compression algorithm by default.

So, I tested #gzip vs #pigz by compressing a text file of the entire bible (4mb). And the results:

gzip: 4885MB/s
pigz (4 threads): 13406MB

Holy moly

I need to #compress a lot of #logfile's, so, again, tested #pbzip2 #lbzip2 #lzip #xz #pixz #pigz and #zstd.
The current winner for time/size race was "lzip -7" (which is same as plzip -7, uses all threads available). #Compression rate slightly below pixz but it's hugely faster (also has better fileformat 😉).
May have been some zstd only if it would be simple to figure out the right combo of 22 options.

Pigz - Compress And Decompress Files In Parallel In Linux #pigz #gzip #zlib #pthread #compress #decompress #opensource #cli #Linux
https://www.ostechnix.com/pigz-compress-and-decompress-files-in-parallel-in-linux/

I have a 20GB disk image of sparsely populated data -- less than 2GB used.

The pigz (parallel gz) compressed it into a 2GB file in 1m 30s on 4-CPU 8-Thread CPU from an NVME drive.

```
pigz -5c -b 4096 diskfile > diskfile.gz
```
-5 -- level of compression (0-9)
-b -- blocksize (default 128K)
-c -- write to stdout (keep the original)
