How does QuestDB get the kind of performance it does, and how are we continuing to squeeze another 50-60% out of it? We are constantly learning more about the fundamental concepts of memory performance, and this is one example of how what we at first thought would be worse for performance ended up bringing us a rather substantial boost in overall memory performance.

We will walk you through how some of our initial thoughts on storage and memory-mapping evolved to bring us better performance overall.
