I do wonder if someone could hack the roms to improve the lun scan. It may just be the hardware can't do it faster. I suspect its just down to a case of a old, slow controller that was not very good to begin with.
The wd33c93 chip was used by a lot of high end hardware, it's very likely that it's a software issue. Whether it's one that can be solved within the confines of AmigaOS is another matter.
