I've encountered at least one structure where a boolean flag is 64-bits in size on 64-bit builds. If we really want to go to the last mile we might want to also evaluate things like tagged pointers; there's probably some KiB's to be saved there too. There's also more than one place where we're using strings to identify stuff where we could use enums/integers instead. And yeah, my much delayed refactoring of the observer service got a lot higher on my priority list after reading this thread. Gabriele
