Basic Website Optimisation through .htaccess

We can optimise the website speed by placing following code on the htaccess

<ifModule mod_gzip.c>

  mod_gzip_on Yes

  mod_gzip_dechunk Yes

  mod_gzip_item_include file .(html?|txt|css|js|php|pl|otf|ttf|woff|svg|eot)$

  mod_gzip_item_include handler ^cgi-script$

  mod_gzip_item_include mime ^text/.*

  mod_gzip_item_include mime ^application/x-javascript.*

  mod_gzip_item_exclude mime ^image/.*

  mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
