We've been hearing for a while that SEO may be affected by the time your page takes to load - so recently we've started an intensive exercise of getting our websites to load in the absolute minimal time possible. Our belief is that the current load speed and rating in GTMetrix is relatively good: 85% for PageSpeed, and 95% for YSlow Grade and a load time of 1.29 seconds, so we thought we'd share how we did this. Some of these are Joomla! specific, but the general concepts apply to ANY content management system and any website.
