  • For those who doubt the power of gzip!

    Well, I was surfing through my webalizer stats and I found an interesting chart that shows the growth of my site, including bandwidth. Bandwidth is the bottom one, as you can see, it makes a sudden drop on the 8th... that's when I turned gzip on. Despite my site nearly doubling in growth since then, my bandwidth is still less than what it was before I turned it on!!! Pretty cool... if I haden't turned it on, my bandwidth would be pretty high. gzip rocks!!! On a related note... can anyone tell me why most sites (including vBulletin.com) don't take advantage of this? Wouldn't it save them tons of bandwidth? Is there something i'm missing ???

    I was using it from day one but recently just began to have a problem with a header error, see my post in the trouble shooting forum.I have turned it off for now, just to see if it solved the problem. I have noticed a speed increase since turning it off, now wait and see how my bw goes up

      This is the kind of stuff i'm worried about. So far I haven't had any users complain about a header error... but who knows. Is the header error problem a browser compatibility problem with certain users or is a server problem? Anyone? I'm running the latest version of apache and like I said, I don't think there have been any problems with it yet. GZIP speeds up my forums alot... I just turned it off now and my forums were noticibly much slower, so I turned it back on I don't want to have to turn gzip off.

        GZIP is fine if you capacity on your webserver[s] to handle the increased load.

        If your webserver is churning because HTTPD is queing for the processor rather than serving your site will be slower WITH GZIP

          lol funny thing is my forum sped up when I turned it off lol

          The 2 members who were getting it use the same cable provider and from the same area and one was using the proxy (not sure of the other) As well one of them has his own forum and was getting it there as well. We are on different servers I posted a message letting him know about the answer I got here and asked him if he had gzip on, havnt heard back from him yet.

            Yes, there's something you're missing because this site does use gzip compression.

              Thats odd.. I used that same site like 2 weeks ago to check vbulletin and it said it wasn't using it. Either gzip was just put on recenetely or else I mispelled the url. Anyways, that's good that vb.com uses it... fills me with a bit more confidence

                It's always used gzip as far back as I can remember.

                  It was turned off for a brief period (a few days) a few weeks ago if I remember correctly. I can't quite remember why but I do remember it being mentioned.

                    Also, you have to include a trailing slash for it to work:

                    http://www.vbulletin.com/forum shows as not gzipped.

                    http://www.vbulletin.com/forum// shows as gzipped.

                    This is because the first page is simply an Apache redirector that forwards you to the second page.

                      Ah, there lies the problem

                        Ah, the wonders of GZIP I use almost 1GB bandwidth everyday with GZIP ON. So I'm scared about how much I'd use with it off! It compresses pages down from 70kb to 10kb!
