Total image size shouldn't be too big (imageSize)	The page total image size is 746.9 kB. It's really big. Is the page using the right format for the images? Are they compressed as good as they can be? Make them smaller by using https://imageoptim.com/.	50
Total JavaScript size shouldn't be too big (javascriptSize)	The total JavaScript transfer size is 307 kB and the uncompressed size is 1.1 MB. This is totally crazy! There is really room for improvement here.	0
Don't use private headers on static content (privateAssets)	The page has 2 request(s) with private headers. The main page has a private header. It could be right in some cases where the user can be logged in and served specific content. But if your asset is static it should never be private. Make sure that the assets really should be private and only used by one user. Otherwise, make it cacheable for everyone.	90
