Just out of curiosity, did you try with greater than 16?
This is what I want to know too, because based on your numbers, it
looks like 16 is the best of those listed.
I would expect the exact same trend to continue, as in, all three
numbers getting smaller, and the compiler memory usage continuing to
rise. I would also expect the rate of improvements to keep diminishing
as we move to larger values.
Also, I would be very interested in seeing "size of libxul.so" for
fully-optimized (including PGO, where we normally do PGO) builds. Do
unified builds help or hurt libxul size for release builds? Do unified
builds help or hurt performance in release builds?
It make sense for both of those metrics to improve a little bit at least
for non-PGOed code, but the differences are probably very minor.
