This may be placed elswhere but I could'nt find it in this version.

This dead simple mod compresses pages at the server as they delivered to the client browser (if it supports compression) using gzip.

It can give upto 80% reduction in size, so speed download, there is no extra load to server.

There is a option in admin, so if you have that 'on' don`t apply this to the client side.

This can be done for any php document.

In application_top.php both on client side & admin, near the top, after <?php

add:

ob_start("ob_gzhandler");

Thats it, you should notice a speed increase on loading admin pages immediatly, client pages will be faster, especially if using dial-up.

I have`nt found any downside to date.

which browsers don't support gzip?

IE 3 & older, Opera 4 & older Netscape 3 & older, and certain versions of firefox (not sure which)

I already have this in my version of MS2.2

// if gzip_compression is enabled, start to buffer the output
if ((GZIP_COMPRESSION == 'true') && ($ext_zlib_loaded = extension_loaded('zlib')) &&
	(PHP_VERSION >= '4')) {
	if (($ini_zlib_output_compression = (int)ini_get('zlib.output_compression')) < 1) {
		if (PHP_VERSION >= '4.0.4') {
			ob_start('ob_gzhandler');
		} else {
			include (DIR_WS_FUNCTIONS . 'gzip_compression.php');
			ob_start();
			ob_implicit_flush();
		}
	} else {
		ini_set('zlib.output_compression_level', GZIP_LEVEL);
	}
}

Hi, I did mention the option in admin, which controls this bit of code, the point of this tip is to make people aware of this very handy option & how to apply it in admin as well, or any other php pages.

Try it on your admin & see just how much quicker they load.

[NimaP]

wow..i just applied this to my admin.

what a difference in speed! great tip!

[Coopco]

Hey Spooks, thanks. Have seen that option for yonks but never touched it till now. I think load times have halved and I am using the default value of 5..

[WoodsWalker]

This is way cool, Sam. Thanks!

Fantastic tip m8 i never knew what that was for !!!!!!!!!!!!  

[dreakies]

Thanx! Great tip!

[cmakynen]

Wow - that works great - thanks!
Just curious - if an old non-supporting browser opens a page with this code in it. what happens?  It croaks, or it just passes over it?

[dark_tyrant]

What does the unsupported browsers show when using this?

Thay wont show any differance, the server will detect the browser does'nt support compression, so will serve uncompressed pages, so the only differance will be the load speed.

[WoodsWalker]

Even MORE cool!

I am sorry, I donot get clear myself. Hope somebody can help me out.

in admin >Configuration >GZip Compression, if i set to "ture" and the level to "3",

can i still add "ob_start("ob_gzhandler");" in catalog/ admin/includes/application_top.php and catalog/incule/application_top.php

i just confuse i have got speed up in admin after add ob_start("ob_gzhandler");" in catalog/ admin/includes/application_top.php.

Anything i have done wrong?

If you set to true as above then yes still add to catalog/ admin/includes/application_top.php as that setting has no effect on the admin side, but do not add to catalog/includes/application_top.php  as that would generate an error & is not then required anyway.

I hope that makes it clearer.

Thanks Sam very much, your answer make me clear, i did find error when i add to catalog/includes/application_top.php. I really hope i can speed up the client side.

Hello.

Can anyone assist me why my website (www.firstalberta.com) is taking too long time to load the first page/time ?

I applied all suggestions as stated above like turn on GZIP and reduce the image size too.

Please let me know how to tune, it is taking nearly 30 to 40 sec's and i need to load the page in 1 sec.
