Chrome add-on PageSpeed from Google Development team and their Audit states that if a page cannot have the above the fold content delivered to user within a second then the page is less likely to be crawled and indexed.  Makes sense why are results are now low.  Before you state that I should optimize my images from home page, note that has been done, however every page from product cart still results in these bottlenecks from including resources in the head tag.  Regardless of the content on the page, without any images the errors still exist.  This ultimately brings the user a bad experience which is Google's new term for getting to the top requirement.

One of their issues is with the 302 redirect to the service.asp page, giving the empty cart message comment from the msg.asp page.  This event now creates a new bottle-neck/stall from the angular JavaScript.  They recommend a 301, if any, especially on the first page their bot crawls.

Hopefully this is something that will be looked into since Google is the driving force for getting our customers, if not from our two 150 page catalogs we send out every year.  If you inspect element anywhere within Chrome click on the Network tab and refresh.  Comment on your DOM time and Render time below.  Run the audit to see where you stand as well.  If you see results like these then maybe something has to be done.
