Hi!
Compared to 3.4 we get a 340% performance regression because of the
different inline-unit-growth default (50 vs. 150). See PR18704.
Why was the limit set so low? This may cause compile time performance
comparisons to be apples-to-oranges comparisons.
At least fix the docs, which still say 150 is the default.
Thanks,
Richard.
