My Sunday benchmark binge has yielded the following result. Deku is the third-fastest framework on the list! It’s only slower on average (by a hair) than Vanilla JS and Solid JS, and is considerably faster than most popular frameworks.
Deku’s design is heavily biased towards reactivity, and for the reactive benchmarks, it’s often faster than vanilla JS. The tradeoff is that it’s “slow” when adding 10k elements to a table (instead of 3rd fastest it’s 4th!). I don’t think this is an inherent limitation in the framework, it’s just a product where my attention has gone, and I hope to optimize this part of the framework some day.
Deku will be even faster once some PRs land in the backend optimizer, but for now I’m pretty happy with the result
