> HTTP/2 was designed to address this problem using multiple "streams" built into a single connection. Multiple objects can be sent over a stream in parallel by multiplexing them into the connection. That helps, but it creates a new problem: the loss of a single packet will stall transmission of all of the streams at once, creating new latency issues. This variant on the head-of-line-blocking problem is built into TCP itself and cannot be fixed with more tweaks at the HTTP level. [0] https://lwn.net/Articles/745590/ https://lwn.net/Articles/745590/
