Ces deux outils repr\u00e9sentent des variantes multithread du programme gzip, optimis\u00e9es pour fonctionner sur des syst\u00e8mes multicoeurs. crabz se distingue par le fait qu'il est \u00e9crit en Rust, contrairement \u00e0 pigz qui est \u00e9crit en C (et partiellement en C++), et montre un gain de performance significatif, atteignant dans certains cas 50 %.    <\/p>\n<p>Sur la page des d\u00e9veloppeurs, il y a une comparaison d\u00e9taill\u00e9e des vitesses de fonctionnement des deux outils avec diff\u00e9rentes cl\u00e9s et backends utilis\u00e9s.

crabz avec le backend rust est l\u00e9g\u00e8rement (de 5 \u00e0 10 %) plus rapide que pigz.  <\/ul>\n<p>Selon les d\u00e9veloppeurs, outre une vitesse de fonctionnement plus \u00e9lev\u00e9e, crabz pr\u00e9sente \u00e9galement les avantages suivants par rapport \u00e0 pigz :  <\/p>\n<ul>\n<li class=\"l\"> crabz avec le backend deflate_rust utilise un code enti\u00e8rement \u00e9crit en Rust, ce qui est plus s\u00e9curis\u00e9 ;\n<li class=\"l\"> crabz est multiplateforme et prend en charge Windows, ce qui peut attirer davantage de contributeurs ;\n<li class=\"l\"> crabz prend en charge plus de formats (Gzip, Zlib, Mgzip, BGZF, Raw Deflate et Snap).  <\/ul>\n<p>Bien qu'il soit pleinement op\u00e9rationnel, crabz est qualifi\u00e9 par le d\u00e9veloppeur de prototype conceptuel d'outil CLI
