I recently did a test to determine the speed of my website and noticed the following failure & suggestion: Parallelize downloads across hostnames.
Overall, I did fairly well, but nobody likes to see an “F” as a grade and I have no idea why I am ‘failing’ in this area.
Is there anything I can do on my side to resolve this or is it more of a webflow thing? Also, is there anything else I can do based on these results to increase the speed of my site?
This has led the industry to a place where it’s considered Best Practice to do things like spriting, data: inlining, domain sharding and concatenation. These hacks are indications of underlying problems in the protocol itself, and cause a number of problems on their own when used.
However, in 2016, SPDY was deprecated and HTTP/2 was released in its place. While HTTP/2’s increased adoption will eventually make domain sharding obsolete
