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?
Thank you in advance.
