Well it turns out that you're right, but you have missed that you can't
just multiply by the MIPS ratio. Lots of othe rfactors apply, like the
amout of physical memory. How much does the average 11/750 have vs the
average SS2? That could make a huge difference. A 24M 3/60 is much
snappier running X than a 8M IPX, for example.
Anyway, 2 days is still about 47.9 hours too long to change a simple
thing like that.
