jit - What are the advantages of just-in-time compilation versus …
JIT compilation is used during development, using a compiler that is especially fast. Then, when an app is ready for release, it is compiled AOT. Consequently, with the help of advanced tooling and compilers, Dart can deliver the best of both worlds: extremely fast development cycles, and fast execution and startup times.

JIT 为什么能大幅度提升性能？ - 知乎
而且，JIT还可以根据hardware的信息，使用更高级的指令，比如AVX512，充分发挥硬件的能力。 对于很多深度学习应用，模型的input shape等信息在第一次运行的时候就能确定下来，之后维持不变。因此我们可以只在第一次运行的时候做JIT，之后一直run JIT好的code。
对比JIT和AOT，各自有什么优点与缺点? - 知乎
由于 jit 需要在运行时编译程序，所以启动时需要一段时间的预热才能达到峰值性能，而 aot 不需要预热，因此启动时间更短，这对于小型程序和微服务来说很重要。 内存占用更低; jit 编译器需要收集程序信息和编译程序，因此需要一些额外的内存存储这部分信息。
