Bonjour,
Je savais qu'il y avait la compression static et dynamique, et le site parle de 11 niveaux de compression.
Both IIS6 and IIS7 allow 11 levels of compression (actually 'Off' and 10 levels of 'On'). The goal for this post is to compare the various levels and see the impact of each.
Son scénario est bien délimité
To find out the bandwidth savings for the different compression levels, contrast them against the performance impact on the system and come up with a recommended configuration.
Je comprends ça conclusion, cependant je ne vois pas à quel niveau la compression joue son role :
My recommendation is, first and foremost, to make sure that you haven't forgotten to enable dynamic compression. In almost all cases it's well worth it, unless bandwidth is free for you and you run your servers very hot (on CPU). Since bandwidth is so much more expensive than CPU, moving forward I'll be suggesting 4 for dynamic and 9 for static to get the best balance of compression and system utilization. At this setting, I can set and forget for the most part, although when I run into a situation when a server runs hot, I'll be sure to experiment with compression turned off to see what impact compression has in that situation.
Ma question, à quoi correspondent les différents niveaux de compression ? L'agressivité, le taux de compression ?
0 je compresse peu, 9 je compresse beaucoup donc mon CPU est à plein régime ?
Je ne me souviens pas avoir eu besoin de mettre une valeur pour activer la compression, seulement un booléen "true" ou "false"...
