niveau taux de compression le grand vainqueur est <span style="font-weight: bold;">Ocamyd</span>. Par contre il est très long à compresser et il est assez gourmand en ressources (mémoire) c'est pourquoi je vous le conseille uniquement si vous avez peu de fichiers à compresser.<br />Si vous voulez un bon compromis taux de compression et vitesse de compression je vous suggère d'utiliser <span style="font-weight: bold;">p7zip</span> ou <span style="font-weight: bold;">lrzip</span>. Avec une préférence pour ce dernier qui est plus rapide pour la compression (il n'existe pas de version windows). Pour ceux qui utilisent à la fois windows et linux je vous recommande p7zip (le portage linux de <span style="font-weight: bold;">7-zip</span>), bien qu'il soit un peu plus long à compresser.<br />Si vous avez beaucoup de fichiers à archiver sous linux, je vous conseille également lrzip pour sa rapidité ou le bon vieux <span style="font-weight: bold;">gzip</span><span> si vous avez une petite config</span>.<br /><br /><span style="color: rgb(153, 255, 255);">On the level ratio compression the large winner is Ocamyd. On the other hand it takes a very long time to compress and it is rather greedy in resources (memory) this is why I advise it to you only if you have few files to compress.</span><br /><span style="color: rgb(153, 255, 255);">If you want a good compromise between ratio compression and speed of compression I suggest you using p7zip or lrzip. With a preference for this last which is faster for compression (there is not Windows version). For those which use at the same time Windows and linux I recommend p7zip to you (linux port of 7-zip), although it takes a little a long time to compress.</span><br /><span style="color: rgb(153, 255, 255);">If you have many files to archive under linux, I also advise you lrzip for his speed or the good old man gzip if you haven't big PC.</span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6604742441745246467-6612611691286819178?l=howto-linux.blogspot.com' alt='' /></div>Fqbhttp://www.blogger.com/profile/02490556256780187935noreply@blogger.com0
