Well, the results are in! Turning GZIP support on within the forums dropped the bandwidth usuage on forums.mustangworks.com by 500 MEGS yesterday! YIKES! It's definitely a drastic difference, and it has made no negative impact on CPU load on the server. Therefore, I have removed ZLIB from PHP and instead installed the mod_gzip module on Apache. Therefore, ALL the pages on the entire site (dynamic/static/apps) are now being compressed with gzip too. Everyone should now see that the entire site is now faster to download. The only things that are not compressed are images, videos, style sheets, and javascript files.
