Slow content download times for images

[pmeenan]

Yes, that looks like HTTP/2 but it also looks like the server doesn't support prioritization/dependencies and is sending all of the resources down at the same time. Usually for a HTTP/2 server that does support prioritization you will see a long light bar and staggered content download chunks as each resource downloads in priority order.

You won't see it locally unless you slow down your network connection at a packet level (Chrome's internal throttling won't show it).
