I agree on that. It is funny that you often find people spliting hairs on optimizing code like "but templates are slow" or even to the extreme "should I use single or double quotes for strings?", while things like this affect user expirience much, much more. rush -- http://www.templatetamer.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

My lord, this rocks! Our pages load at least twice as fast now, and bandwidth will likely be reduced by at least a factor of 2. I would strongly recommend utilizing zlib compression functions to anyone looking to speed page delivery & reduce bandwidth! --Noah "Rush" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > "Ammar Ibrahim" <[EMAIL PROTECTED]> wrote in message > news:[EMAIL PROTECTED] > > if this works for you, could you please post your story in the group. this > > is very interesting if you could save 50% of your bandwidth just by > turning > > the zlib flag :) > > if you check amount of data that gets transfered from > http://www.moj-posao.net/ (once that images are cached, which is usually > imediately after the first page is loaded) you will see that amount > transfered is is in region of 10k, while the html source of the page is > about 50k.

Hey all.
No such luck re: just using ini_set() to compress pages
Rush's link is HIGHLY useful -- thanks Rush!

Works without a hitch in IE 5+ and NN 4.7+ with PHP 4.2.3

if this works for you, could you please post your story in the group. this
is very interesting if you could save 50% of your bandwidth just by turning
the zlib flag :)
good Luck,

I am not sure about ini_set, I am doing it manually, here is the article which gave me directions: http://www.phpbuilder.com/columns/argerich20010125.php3?page=2 rush -- http://www.templatetamer.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Zlib Compression || Implementation || Bandwidth Savings?
H Looks like the majority of sent bandwidth is html, not image files >> ratio is at least 10:1 html to images. With that in mind, setting zlib compression to ON seems the way to go. Question is, how to implement compression? Is it enough to just ini_set() zlib compression to ON? i.e. will all content be automatically be compressed, or do I need to ob_start() & ob_end_clean() at the start and end of each page? TIA for any clues -- I'm obviously confused about compression techniques. --Noah "Rush" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > "Cf High" <[EMAIL PROTECTED]> wrote in message > news:[EMAIL PROTECTED] > > Having a good problem -- our hockey report site has jumped from 10 > > gigs/month to 30+ gigs/month & growing. > > > > We're getting killed in bandwidth fees at the moment; barring switching to > > another host, will utilizing ZLIB compression significantly reduce > > bandwidth? > > well it depends what uses most of your bandwith.

If it is for images, then compression will not help much since images are allready compressed. In that case, you may save much more if you can put images in some directory and tell apache to allow cacheing for that directory. On the other hand if your bandwith goes mainly on thransfer of html source for the pages then compression can shave up to 80% of your bandwith usage. rush -- http://www.templatetamer.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
