Dart Reactivity Benchmark

Benchmark comparing different standalone Dart reactivity/signals frameworks.

Usage

Dart VM

dart run bin/[framework_name].dart

Run all benchamrks

bash bench.sh

Test System Information:

• Operating System: macOS 15.2 24C101
• Model: Mac15,10
• Memory: 36.00 GB
• CPU: Apple M3 Max

Score Ranking

Rank	Framework	Score
1	state_beacon	28.56
2	alien_signals	26.03
3	preact_signals	18.78
4	signals	17.25
5	solidart	6.38

Ranking algorithm

1. In the same test case, the fastest framework gets 1 point, and other frameworks get relative scores by dividing this score by their own scores
2. Relative score = benchmark time / execution time of the framework
3. In order to get the overall performance of each framework, I add up the relative scores of the framework in all test cases to get a "comprehensive score". The higher the comprehensive score, the better the overall performance of the framework.

Performance benchmark results of each framework (unit: microsecond μs)
