    Project mention: Guido van Rossum: Faster CPython (2021) [pdf] | | 2022-01-23

    Choosing a language is a significant factor towards the performance of your services.

    A service built in go can req/resp up to 30x faster than one built in python.

    I know benchmarking isn't always the greatest, especially when the previous maintainer of Actix-Web (Rust) kind of cheated to get to the top of the leaderboard, but it still provides a decent general overview of how many responses/s a service can handle when using the same box.

  • fastexcel

    Generate and read big Excel files quickly

    Project mention: how to create an excel file from a form in an android app | | 2021-12-14

    I would use some library like for example this one. So you collect all the data you want to store in a list or map, and iterate over it, then add them to the excel like shown in the documentation of the library (should always be the same way more or less for any library)

    Project mention: OptiFine alternatives? More specifically looking for mods that allow for OptiFine textures. | | 2022-01-23

    I like custom textures but so many of them require OptiFine. I already have a bunch of OptiFine alternatives. I have Sodium, FerriteCore, C2ME, LambDynamicLights, Starlight, and Sodium Extra. I have looked at Animatica but that only allowed for animated textures. Do you guys know of any mods that allow for OptiFine textures but work with my performance mods?

    > Software benchmarks are super subjective.

    No, they are not, but they are just a measurement tool, not a source of absolute thruth. When I studied engineering at ETH we learned "Who measures measures rubbish!" ("Wer misst misst Mist!" in German). Every measurement has errors and being aware of these errors and coping with it is part of the engineering profession. The problem with programming language benchmarks is often that the goal is to win by all means; to compare as fairly and objectively as possible instead, there must be a set of suitable rules adhered to by all benchmark implementations. Such a set of rules is e.g. given for the Are-we-fast-yet suite (
