There are 215 open runtime performance
(out of a total of 1655 open tickets, that makes 13%).

Compared to say new typesystem features, they don't get much attention.
Only a few were fixed

<https://ghc.haskell.org/trac/ghc/wiki/CodeOwners#CurrentOwners>?). He also
created https://perf.haskell.org/ghc.
