I've built an efficient in-memory database. It has to be very low latency on batched queries. When I couldn't squeeze more perf out of it myself, I tried enabling large page support (dotnet on Windows) and instantly got a 10% perf increase. It was not at all a pleasant experience due to lack of documentation as well as the flaky implementation. But I was surprised by how much overhead the TLB accounted for.
