Hello, The new M1 machine gcc103 was initially running with a 4 KB page size kernel, but we switched it to 16 KB on 2022-03-13. 16 KB is the native page size for the hardware, and running a 4 KB kernel requires a patch [1], see [2].
There are reports that running with 16 KB page size speeds up some tasks (especially compilation) by about 20%. However, some software assume a 4 KB page size and won't work at all with 16 KB. Some don't expect build-time and run-time page size to be different. There is a recent effort from the Asahai project to collect and fix such issues: https://github.com/AsahiLinux/docs/wiki/Software-known-to-have-issues-with-16k-page-size It's possible to contribute there if you feel like it.
