I have launched the PageSpeed Insight tool and I have several tips to improve performance but most refer to:
"Does not use passive listeners to improve scrolling performance" -> But the only file that marks me is a utils from the google maps api
"Serve static assets with an efficient cache policy" -> The only files that mark me are from the googe maps api and the google analytics
"Remove unused CSS" -> But I only have one css for the entire web page (not all the css acts on the entire page, if not depending on the url in which you are there will be elements that appear and if it will take the css which for example does not take in the home page)
Any suggestions?
