AOT isn't for the first 100ms, it's to avoid the 10K invocations required on a method for HotSpot to determine a hot code path and optimize the method - that can take a lot longer than 100ms and why when you see the JVM used in the financial sector, for example, they go through a lot of effort to "warm" the JVM.

Of course without runtime profiling the AOT built code may not be optimized for the hot path correctly, HotSpot will still deoptimize in this case and begin profiling again - so it's not going to be suitable for everything until they allow you to capture profiling details and feed it into the AOT compiler.
