Improving pagespeed

I have a website in wordpress with Sydney Pro theme.
I´m triing to improve my pagespeed but in a analysis in PageSpeed Insights it apeears this messages:
Compression in js/jquery/jquery.js
Compression in theme/sydney-pro/style.css
Compression in sydney-pro/js/scripts
Compression in fonts/font-awesome.min.css

What i can do to modify this?


Dear Nuno,

Thank you for asking. It isn’t recommended editing those file. Otherwise, your your changes will be overridden once your theme gets updated in the future.

Try to minify/compress those files using the W3 Total Cache plugin instead.

I hope it helps.
