These days perfetto can load .ninja_log directly without conversion. Attached
is an example of the output.  Also attached a local .ninja_log to upload if
somebody wants to look at the interactive output without building.

That's still the biggest "slowdown".  Only a small number of things can start
before genbki is done. Parts of pgport, bison/flex and parts of the docs
build.

That's gone now.

But these are still present. When building just the backend, the build speed
is limited by gram.y->gram.c, gram.c -> gram.o, linking postgres.
