Hello,
Do you want to enable Gzip? If so, You can Enable Gzip in the .htaccess file by adding:
==============>>>
#Gzip
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript text/javascript
</ifmodule>
#End Gzip
==============>>>
Normally it's enabled by default (Server-Wide), if not, please contact your server admin/hosting provider to enable this module.
Thank you,
