if you've got a few hundred K of unused RAM available, try doing
addbuffers xyz: 400
where xyz: is the amiga partition containing your fake ms-dos partition file.
it's almost respectable after you do that.
the reason is that the filesystem can't keep enough data (filesystem linkage
blocks and such) in memory to efficiently do random seeks on a large file
(10 meg) unless you give it lots of buffers.
