Hi Thomas,

You should checkout the compression of JS which is enabled by default in
4.4 for the backend. Maybe that is what is slowing things down. It
should run only once and then be fine. Can you try disabling that? I
noted on my machine that that was taking a 'little' time on first
requests in the new backend.

It would also be great if you could get some profiling information that
shows what resources are slow to load etc.

Can you get some output from Firebug to try and pinpoint the problem?
