Many of u might be doing the same. I dont know. But i found this nifty tweak which i would like to suggest.
When i added CDN to my site, i saw that one of the top files which was being loaded was dashicons.min.css which is a dashboard ADMIN Bar css. However, this dashicons.min.css was being loaded for everyone. Even for normal readers.
So i added this rule to functions.php
And now the dashicons.min.css is not loaded for front end users. Simple tweak but in the long run, might save GB's of space and might increase site speed by a set percentage.
If u want to see the effect of dashicons.min.css then kindly run your site through pingdom.
