I don't see how 62 seconds rather than 60 is anything close to going off the rails. Did I read something wrong? This sounds more like a minor wibble.
"Off the rails" was a rhetorical flourish; indeed a single program regressing by 3% isn't a catastrophe. That being said, runtime performance improvements are hard-won prizes. Consider that the largest allocations improvement arising from the "Compiling without Continuations" paper was ~8%. Consequently, if someone comes along with a 3% regression we would remiss not to take it seriously. Cheers, - Ben
