Reflections on software performance - Made of Bugs
I’ve really come to appreciate that performance isn’t just some property of a tool independent from its functionality or its feature set. Performance — in particular, being notably fast — is a feature in and of its own right, which fundamentally alters how a tool is used and perceived.
This is a fascinating look into how performance has knock-on effects beyond the obvious:
It’s probably fairly intuitive that users prefer faster software, and will have a better experience performing a given task if the tools are faster rather than slower.
What is perhaps less apparent is that having faster tools changes how users use a tool or perform a task.
This observation is particularly salient for web developers:
We have become accustomed to casually giving up factors of two or ten or more with our choices of tools and libraries, without asking if the benefits are worth it.
