Cache Management Lessons Learned

• lrossi 6y ago
  > So at least on Linux, cache performance hasn’t been an issue with LMDB. It’s noticeably worse on Windows, as is memory management in general on Windows, but obviously Windows is not a high performance platform to begin with. This made me smile.

    It's also why "just run WSL" or "just run Linux in a VM on OSX" is unsatisfying. The performance characteristics are quite different, which makes a big difference if you're trying to reproduce a race condition.

  One thing I've seen smart developers do on multiple occasions is unknowingly throw out their ability to reason about their code while adding caching ( https://softwareengineering.stackexchange.com/questions/351244/easy-to-reason-about-what-does-that-mean https://softwareengineering.stackexchange.com/questions/3512... ). Then when some weird bugs start showing up it's like "Ummm... this shouldn't be happening" and then end up having to restart _everything_ because the interplay between layers of caching and the rest of the program no longer make any sense.

  What the hell is going on with the line breaks there? That's painful to read on mobile
