Not really, I am trying to see that `-Xint` does not have easy to fix impediments to cold performance. In this benchmark, bootstrapping stuff had already happened at warmup, it measures the overheads of doing all the MH/VH without the optimizing compiler assistance. ------------- PR: https://git.openjdk.java.net/jdk/pull/7333
