strongly agree it's important to make sure your code base isn't doing anything dumb, like O(n^2) iterations, or 1000 sequential RPCs instead of 1 batch RPC, or

strongly agree it's important to make sure your code base isn't doing anything dumb, like O(n^2) iterations, or 1000 sequential RPCs instead of 1 batch RPC, or etc -- this is i guess your point about architecture but assuming that bar is cleared, performance optimizations should only be accepted when accompanied by benchmarks/profiles that demonstrate their usefulness at the whole system level
