I don't think Trump made his money doing low-level performance programming for the past 10 years, so I'm not sure your analogy is valid. However, since you, whoever you are, have not only written a hash table, but discovered profundities like 'Sometimes list costs 780x as much as vector for "absolutely zero reason"', and 'don't try to offload 100 cycles of work to another thread' I'm going to defer to your expertise. I recommend you stick a bone through your beard, pronounce yourself a performance guru, and make bank. Have fun. |

:-) :-) I LOVE when my opponent has to resort to personal insults :-). Leaving aside any sarcastic remarks in this regard:
For Intel's sake I Really Hope that these "profundities" are indeed very well-known to you - and believe it or not, they're very well-known to me too for at least 10 years. However, this is not the point; the point is that there are LOTS of developers out there who do NOT know them - and the OP is intended for them (and not for "performance gurus").
It is actually THIS simple. Eliminating 90% of inefficiency does not really require black magic or "performance gurus" who know exactly how the pipeline of specific CPU works. And this is exactly what I'm arguing for - to educate app-level developers and architects about this low-hanging fruit of 10x+ inefficiencies; I can assure you that it is very far from being universal knowledge in app-level development circles.
