Also, reducing the number of directories that are PGO/LTCG should mean that the rate of growth decreases proportionally. Even more than proportionally, if we flip our default for entirely new modules to be non-PGO/LTCG, as I assume we would. Rob -- Jesus called them together and said, “You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them. Not so with you. Instead, whoever wants to become great among you must be your servant, and whoever wants to be first must be your slave — just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.” [Matthew 20:25-28] _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
