- Subject: More on MacMinix, gcc?
- Lines: 22

- Well I found my changes(all six lines) that will cause MacMinix to call
- the device driver directly for IO, rather than just reading a file when
- it wants to do disk IO. The change did NOT help the IO rate though :-(
-
- I should have guessed this since my ramdisk goes about 6x the speed of
- my hard disk, and the IO rates in MacMinix to the ramdisk are only about
- 1.8x those to the hard disk. I guess there is just so much overhead that
- removing a little of it does not help all that much.
-
- I have gcc 1.39, and would like to know if going to 2.x would be worth
- the effort. Can some kind person who has 2.x on a 68K system please post
- some benchmark numbers for the resulting code from the new gcc? If possible
- also use -m68020 since I find gcc to out perform c68 by a wide margin only
- when I use -m68020(ie use 020/30/40 instruction set instructions also).
- (I still don't know which ftp site the ported 2.x is on:binary please I
- don't want to recompile gcc)
-
-
- BTW, the next version of MacMinix is being delayed a bit since some new
- features are being added, not because the author has fallen off the
- face of the earth again.
