Re: Do you want a faster gmmproc?

I have filed bug 646820 gmmproc: Increase speed by processing many files
in one invocation.

Ok, I don't do it every day, not even every week, but when I update my
local copy of gtkmm with 'jhbuild build' it often regenerates and
recompiles all or most of glibmm and gtkmm (as well as glib and gtk+,
which is also time-consuming).

Right, my modified gmmproc has no concurrency. I have an old-fashioned
PC with a single-core processor, and I didn't even think of concurrency.
If you update only 3 files, I guess it doesn't matter much which
alternative you choose. Even the present gmmproc without concurrent
processing is fast enough.

Krzesimir, you have mentioned at that you plan a
major rewrite of gmmproc. Do my ideas for a faster gmmproc in any way
clash with your plans? I don't want to make your job more difficult.
Would it be better if you rewrite gmmproc first, and only afterwards we
add new features? Such as this one, and the one I've proposed in bug
86864 "enums should be inside classes"
