On my PC, which is twice as fast as a Sun-3, I wish for faster
integer and floating point in equal measure. Some of my scientific
code is integer-bound (multiplies and divides). And, I surely
would like TeX to run faster (and it is mostly fixed point). A
30% gain going from a MS-DOS 16 bit TeX to a full 32 bit
one was quite noticeable. And, believe me, I would like LOTS
faster performance on this Pyramid where I use Notes (its OK today -
but this is spring break!)
