Speed up your site

I have found a way that increases your site speed
Go to admincp-cms-blocks-add new block

product-core

module custom

title-leave it empty

type-PHP code

controller-non(sitewide)

placement - block 1

PHP/HTML Code (Optional) :
<?phpob_start("ob_gzhandler");

NOTE DONT PUT ?> or it will crash your site

DONE if it worked rep me
