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

[Elliot Saba]

Thanks Pierre, I don't really know what to look for in the profiler, so
I've attached the result of a 90 second run with a few builds going on at
once, and me loading a few views toward the beginning of the trace, in case
you're interested in looking it over.  Enabling HTTP2 and switching over to
postgresql has had a positive effect for sure though, so thank you for the
recommendations.
