*Benchmark results here. Diagon performs consistenly 2x-8x faster than Immer even without Immer patch support enabled. Note, of course, that any benchmarks should simply be treated as a data point and will never be a substitue for real-world profiling. Suggestions and improvements to them are very welcome. A React benchmark on js-framework-bench pull request is pending.
