AOT is actually often slower than the JVM because it doesn't have runtime profiling. It is possible to use AOT with runtime profiling (i.e. run your app in some real world manner, capture the data and then AOT with the runtime data). But the point here is that JVM (and V8 actually) can do more than simple compiling by understanding the nature in which the program runs and therefore be quite fast often making up for the fact they are VMs.
