We have preliminary data on a subset of benchmarks which suggests it's a combination of loading more classes and spreading the work across a larger set of methods, which means we need to warm and JIT more methods to reach peak performance. ASM is a smaller library with a more minimalist approach, so it loads faster and gets up and running a bit faster. We'll probably need to file regressions as they are detected for tracking purposes, but I expect we'll continue chipping away at and improving the classfile API in the months to come. ------------- Marked as reviewed by redestad (Reviewer).
