A few months ago I moved over all my Apache configuration files to native LS configuration. When I did, my bandwidth dramatically increased: The old apache setup was using mod_deflate, but the new LS setup is set to use gzip, so I'd expect the two setups to be similar. Just to verify that gzip was working today I turned it off for 20 minutes or so, and sure enough my bandwidth jumped up another 500 kb/s. On the flip side, I tried this gzip detector on my site (forum.rpg.net) and it says that there's no gzip running: http://gzipcheck.jgate.de/ Result: BAD: not using gzip encoding Headers: Transfer-Encoding["chunked"] Connection["Keep-Alive"] Content-Type["text/html; charset=ISO-8859-1"] Expires["0"] Set-Cookie["PHPSESSID=7701bb2f9d6baaf7ef624860228bf79a; path=/", "bb_lastactivity=0; expires=Tue, 31-Mar-2015 21:08:55 GMT; path=/; domain=.rpg.net", "bb_lastvisit=1396300135; expires=Tue, 31-Mar-2015 21:08:55 GMT; path=/; domain=.rpg.net"] Pragma["no-cache"] Date["Mon, 31 Mar 2014 21:08:56 GMT"] Keep-Alive["timeout=5, max=100"] Server["LiteSpeed"] null["HTTP/1.1 200 OK"] Cache-Control["private, post-check=0, pre-check=0, max-age=0", "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"] X-Powered-By["PHP/5.3.27"] Color me confused. Just to make sure that nothing further is going, I used "iftop" to look at my outgoing bandwidth, and it looks to be all www traffic (mostly crawlers, GRR), which suggests that LS just isn't offering the same amount of compression that it used to when I had it running an Apache configuraiton. Any idea how to debug this and/or get the bandwidth back to where it used to be?
