Looking for an article on premature optimization

Question

Search Engine Optimization

Many years ago, I read an article by a certain friend who, back in the 60s (if I don’t confuse anything), worked as a programmer in the USSR, and there, using very vivid examples, he tells how to and how not to optimize the code. Unfortunately, the link has not been saved. If anyone knows what this is about, please let me know.

Answer 1

My subjective opinion is that premature optimization is important only on obvious flaws in the system (a lot of data, obviously complex algorithms, too many connections, etc.) Optimize the rest when it is needed.
And I will answer in advance the most frequent question in this regard: - what if it becomes more difficult to do optimization later? - Make the architecture so that it is easier (weak coupling, entity extraction, etc.)
