I have a sinking suspicion that Facebook's Messenger webapp is doing exactly that - its UI has been very laggy for me in the past months, and the issue persists through refreshes, browser reboots and system reboots.

It's the only thing that makes sense. I mean, they couldn't have screwed up a chat client that badly...

They don't have the same depth of experience in developing chat apps as some other bay area companies.
