/sync and initial load slow down?

I have joined more rooms so this may just be that but it now takes a solid 1-2 minuites to load after logging in.

I'm hoping b34edba has fixed any regressions. The condition for running the markdown_to_terminal function, which is extremely expensive, was wrong and ran the function for every message.

I'm not closing this to remind me that the results of markdown_to_terminal could be cached somehow or some other way to use that function less. (Write our own terminal renderer from matrix html subset)
