The book "Writing Efficient Programs", by Jon Bentley, is still a valuable resource. See the short subthread starting with a comment I posted here some years ago:

A few people had replied, agreeing with my opinion, and giving some more details. One of them called the book "gold".

I have also posted about the book a few other times on HN, over the years.

Those comments can be found by searching hn.algia.com for comments (not stories) matching the pattern "writing efficient programs vram22".
