Interesting that one of the factor listed in there, the hardcoded page-size on arm64, is still is an unsolved issue upstream, and that forces app developers to either ship multiple arm64 linux binaries, or drop support for some platforms.
I wonder if some kind of dynamic page-size (with dynamic ftrace-style binary patching for performance?) would have been that much slower.
You can run jemalloc configured with 16KB pages on a 4KB page system.
