A week later I'd like to highlight and recognize some of the performance
improvements that have been made:

* Upgrading utfnormal to use native mbstring functions instead of PHP
implementations <> (MaxSem,
James F, Reedy and myself)
* Optimizations to ApiResult
(Daimona, Thiemo, Krinkle and James F)
* Using PCRE for faster UTF-8 validation in Parsoid
<> (Skizzerz and cscott)
* Reducing the size of the ExtensionRegistry cache in APCU
(Krinkle and myself)
* Reduce impact of HookContainer loading 500+ interfaces
<> (Skizzerz, myself, Tim
Starling and Ori)

If I missed any other improvements people have been working on, my
apologies, please share them! I've been using the Gerrit hashtag
"faster-mw-plz" <>
to try and track these.

P.S. reimaging to Buster is 70% complete now.
