Probably I should not have posted this PR even as draft if it is going to get attention as it isn't really ready for that. But yes, I had already measured startup + warmup and noticed that's an issue. It may be doesn't matter so much for OpenType layout as other things that are always on the critical path, but it is definitely a concern. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15476#issuecomment-1702114439
