compressing a website

[jaysin]

Just add these two lines to your .htaccess will increase speed of your website

php_flag zlib.output_compression on

php_value zlib.output_compression_level 9

 

Basically this will compress the website upto level 9 which can be changed to any value between -1 to 9.

 

To use this you must have zlib support enabled :wink:

does it do the same as if I would enable

Enable HTTP GZip compression in admin - configuration?

any disadvantages at all if I enable it?

 

thanks 4 any help :)

Admin settings affect the catalog only. With this you can speed up the admin side too.

Very rarely will you want to compress to a level of 9 as the extra work the server has to perform reduces any benefit.

 

Typically a setting of 1 or 2 is more than adequate.

 

GZip test your site to find the optimum setting.

 

Remember that the more compression that is put into effect the more work the server has to do for every request. When you have a lot of users requesting a lot of pages, your site will be slower than a snail if the server is trying to compress every page that much.

 

As with everything, there is a point of diminishing returns and 3 is usually the limit with GZip.

Hi, Daemonj

 

GZip test your site to find the optimum setting.

 

thanks for the above test link. Yes you are right about setting up to level 1-2 has almost same effect and will only increase by another 2 to 3% compression if we setup to level 9.

does gzip have to be enabled for this to work?

how do i know if i have zlib support?

Dear Jim:

 

Thanks for the link (interesting tip!).

 

I know the level of compression I must put into my web.
