The spell checker seems to use sync IPC messages. A lot of them. With the spell checker and e10s enabled, there's a pause of several seconds during initialization of https://public.etherpad-mozilla.org/p/berlin-lunch, right after the pad's content shows up. With either disabled, that pause goes away. See the profile at https://perfht.ml/2mPfFC1. (But note that that also is very slow, see https://github.com/devtools-html/perf.html/issues/172) Perhaps it's possible to batch spell checking requests, or make the messages async?

Blake has a patch to mitigate the problem under bug 1303749 I think. Could you please check if it helps and dupe the bug if it's the same issue?

The issue is so obviously the same though that I'll just dupe this.
