--- Comment #10 from Arnd Bergmann <arnd at linaro dot org> --- (In reply to Arnd Bergmann from comment #9) > "-fsched-pressure" on mips64 helps a lot > ... > On arm and aarch64, "-fsched-pressure" has no effect I realized later that on arm and aarch64, -fsched-pressure is enabled by default. Disabling it on these two makes it as bad as mips64, which has it disabled by default.
