- I agree, quite informative.
-
- There was a quite disgusting detail in the article about memory management -
- there the VM port to the R4000 chip. It appears that MS has decided to
- make the very powerful R4000 fit into the mold of the 386 by just about
- ignoring the R4000's native VM support (which is less complex than that
- of the 386, but is just as capable) and emulating _in_software_ the
- multilevel page table system that the 386 uses. Presumably this was done
- in order to lift a lot more code from the 386 VM code than otherwise,
- that is, to shorten development overall time.
-
- I wonder what kind of a performance hit this causes. Is it worth releasing
- NT for the R4000 if it has inferior VM compared to other existing operating
- systems (UNIX, for example).
