[users at bb.net] Nine performance worse than 0.8.14

Hi Elliot,

I was looking at such slowdowns yesterday on nine.buildbot.net
For example https://nine.buildbot.net/#/builders/2/builds/87278 take
300-600ms per http request. Which makes the full page load to 20s !

I am not sure yet what is the reason, as when I built nine.bb.net in the
first time, things were much much smoother.
The DB now has 90k+ builds so this might be sqlite not scaling. I need to
do more tests.

An easy way to speed up the UI is to enable http2
https://github.com/buildbot/buildbot-infra/pull/167/files

You can also run https://github.com/tardyp/buildbot_profiler and tell us
what you get.

Regards,
Pierre
