Is there a specific use case where you need the nice value increased? Realize that we're also running in SCHED_BATCH mode, which also affects how the processes are scheduled. We didn't really see any build time changes when we switched this, only an increase in interactivity when using the desktop while building a build.
If you did want to change this, it looks like we'd need to upgrade our nsjail prebuilt (with this change <https://github.com/google/nsjail/commit/494a5f63cdbb91565e8233133c345280687bd451>), then you could add "--nice_value", "0", to the argument list here <https://cs.android.com/android/platform/superproject/+/master:build/soong/ui/build/sandbox_linux.go;drc=0506361a60215defc5098a6253fdc8f51371ce88;l=158> . - Dan On Wed, Aug 18, 2021 at 10:40 AM Longping Tang <[email protected]> wrote: > Hi Dan > I want to increase priority when building aosp.
