QOTW: "But there's another principle at work here that's less well known, and that was first articulated to me by Robert Dewar: You can remove linear factors by profiling, but it's much harder to undo bad algorithmic decisions. In particular, whether a program runs in O(n) or O(n^2) sometimes depends on decisions that have to be frozen fairly early in the design." - Andrew Koenig Comparing the performance of the same algorithm using many compilers: CPython, psyco, Cython, ShedSkin, Unladen Swallow, Java, C and D: http://groups.google.com/group/comp.lang.python/browse_thread/thread/8d793c4...
