Comment:
Just generally: Of course booting in emulators is way faster than on real
hardware. Particularly off CD. Those are abysmally slow media
(particularly the seeking), while the on-HD images emulators use can be
accessed with full HD speed (and a potentially cached by the host OS).
E.g. on my machine under Linux from entering the qemu command line until
Tracker and Deskbar show up 8 seconds elapse. On the actual hardware I
don't even get fully through the BIOS initialization in that time, and
booting Haiku itself takes way longer due to hardware discovery and
initialization.
Anyway, in r36495 I enabled a special cache for CDs (given that enough RAM
is available -- 256 MB is somewhat on the tight side). On my machine (Core
i7, 4 GB RAM) booting off an anyboot CD takes about 1 min 10 s to the
ReadOnlyBootPrompt, getting from there to the Desktop takes about 10 s,
the background scripts (mimesetting and ssh key generation) are finished
about another 40 s later.
I think that's acceptable for CD boot, but YMMV, particularly depending on
available RAM and CD (drive) speed.
