What programs do people use to benchmark optimizing C compilers? What sort of percent speed improvement is thought to be good? If you mail to me, I'll summarize to the group. Thanks!

The degree of speed improvement depends on the optimizations. If you're just adding a peepholer, 10% is OK. If you're going from a real dumb generation scheme to a real smart one, you might get a factor of five or more.
