I second this. When I do some quick stuff at home or at work, a small ditch in performance is okay, if I spend less time coding. But I know a few people (researchers) with access to >1 PetaFlop/s clusters. Being hit with performance degradation is possibly an issue there: More power consumption; other people need the system, too; as an individual, you might have limited cluster time available. Of course this depends if 1% is to be expected, or 20%...
