I don't get it. What kind of machine was that on? Here are my numbers: [bdwheele@thor parrot]$ ./test_prog mops.pbc Iterations: 100000000 Estimated ops: 200000000 Elapsed time: 11.016154 M op/s: 18.155156 [bdwheele@thor parrot]$ ./test_prog mops_p.pbc Iterations: 100000000 Estimated ops: 200000000 done Elapsed time: 14.288639 M op/s: 13.997134 My I-regs one is slower than yours, and my P-regs one is faster...this is on a P4/1.7G under Linux 2.4.15pre8 Any ideas?
