JITs get to analyze both code and data and optimize for each machine deployed to. A static compiler can only analyze code and the machine used for compilation. If dependencies were pre-compiled, the static compiler won't be able to optimize their relationship with the project. If the machine is changed for deployment.

More information means better optimizations. JITs FTW.

JITs also tend to optimize for compilation time over final performance. Doing ahead-of-time superoptimization or polyhedral loop transformation isn't going to happen in a JIT.

There's no restriction on the kind of optimization a JIT can do. Perhaps there's a current implementation tendency. In contrast, ahead-of-time (data- and platform-ignorant) compilers are restricted.
