Solid's diff algorithm generally is faster(or atleast very comparable) than Mithril's. We test very well in list benchmarks like: https://krausest.github.io/js-framework-benchmark/current.ht.... We are also fast at node creation using pre-compilation to prepare the nodes in a way that can be created more efficiently.
Interesting, thank you for the links and clarification. May need to revisit solid then! What about rendering things that aren't rendered by solid, like markdown rendering via commonmark? Also, Mithril streams is a huge part of my app, will I miss it with Solid?
Hey Solid's reactive system uses Signals which are different than streams but work in similar use cases. Streams are slightly more oriented to transformation than synchronization. Most stream libraries could be used with Solid with a bit of an adapter on the end to connect to the templates as they are a good tool for managing global state.
All that being said. If you are happy with Mithril stick with it. It sounds like it's done everything you needed. I have a lot of respect for it's minimalist approach and its author is one of the most insightful and helpful people I've come across since getting into JavaScript frameworks.
If you are interested in trying something different. Check out our tutorials on the site and see how you feel about it. It is a little bit different type of framework.
