Oh I was just wondering if you were using a caching plugin - you may not need to install one, that is up to you.
Based on my quick analysis it looks like your site is making ~45 HTTP requests for js and css. This isn’t horrible but it is a factor in your overall load time
update: I ran some more tests and notice that your google score is now 61/62, which is an increase from what you initially posted. Additionally, my GTmetrix scans show that your site is now loading in ~4 seconds, which down from 8 seconds from my initial scan. You can view the report here > history tab > page timings.
