- 27. 아이디어의 시작은… • JVMs do all optimizations online at JIT time: - Hugely redundant across runs - Applications launch slowly - What if we could do heavy lifting at install time? ! • Problem: Java bytecode is too limiting! - Memory safety prevents some optzns (eg. bounds checks) - JVM type system doesn’t lend itself to machine optzns
- 28. With some sort of low level virtual machine, we could optimize better and a JIT compiler would have to do less work online! “ ”
