Fast Software

30 Jul 2019

Read this piece today - Fast Software, the Best Software.

Software that’s speedy usually means it’s focused. Like a good tool, it often means that it’s simple, but that’s not necessarily true. Speed in software is probably the most valuable, least valued asset. To me, speedy software is the difference between an application smoothly integrating into your life, and one called upon with great reluctance.

Speed and reliability are often intuited hand-in-hand. Speed can be a good proxy for general engineering quality. If an application slows down on simple tasks, then it can mean the engineers aren’t obsessive detail sticklers. Not always, but it can mean disastrous other issues lurk. I want all my craftspeople to stickle.

I love software that does this: Software that unbloats over time. This should be the goal of all software. The longer it’s around, the more elegant it should become. Smooth over like a river stone.

But why is slow bad? Fast software is not always good software, but slow software is rarely able to rise to greatness. Fast software gives the user a chance to “meld” with its toolset. That is, not break flow.

It feels — intuitively — that software (beyond core functionality) should aim for speed. Speed as a proxy for efficiency. If a piece of software is becoming taurine-esque, unwieldy, then perhaps it shouldn’t be a single piece of software. Ultimately, to be fast is to be light. And to be light is to lessen the burden on someone or some task. This is the ultimate goal: For our pocket supercomputers to lessen burdens, not increase them. For our mega-powered laptops to enable a kind of fluency — not battle, or struggle — of creation.

Such a brilliant essay. Agree 100%. Fast software makes the user feel good about themselves.
