- Images are super small.

- You can do exactly the same level of performance with http://instantclick.io/ to prefetch pages and aggressively cache content on the backend.

- The only dynamic functions are the cart ( session ) and the search. The rest is just navigation.

- There is quite no content

This leaves out what is imho the most impressive part of McMaster website: the deep taxonomy of products and super detailed search with custom criteria per product type and sub type. This is the part that is the most amazing for me and the most complex on an e-commerce website to build *AND MAINTAIN* over time.

If we compare to normal e-commerce use-case, it's lacking a lot of features that have deep impact on website speed:

- No analytics and marketing tracking ( ecommerce without tracking is not realistic performance wise )

- No image gallery, no high resolution images

- No product description

- No product recommendation

- No faceted search

etc...
