Agreed. A good point that people often miss. We also are often in constant pursuit of the next feature, so don't have the luxury of the kinds of polishing or optimization that might get some of those real performance gains. I was a big fan of the accidentally quadratic tumblr. It's important to remember though that not all significant performance gains come from better algorithms, I've taken an industry standard C implementation of an algorithm and improved perf (as measured on production workloads) by 30x by thinking about issues that didn't really concern the original author (in particular cache locality and realizing that the entire problem could be moved into the integer domain)
