After writing this post and asking the question i found some more info and answered my own question below you will see my
.htaccess file you can copy it and use on your site if you like.
Here is what my .htaccess file looks like my site is running really well with these tweaks only thing on mine the standard site wont use is the RewriteCond %{REQUEST_URI} !/sitemap\.xml
with these tweaks my site went from a score of 41 on google page speed test to a 76 as you can see thats a major improvement...
