I created a PR[1] to improve performance of decompressing jimage files, and got very good results. I used `jlink --compress 1 --add-modules jdk.compiler` to generate a javac runtime image and then used it to compile HelloWorld twenty times, this PR reduces the total time from 17830ms to 13598ms (31.12% faster).
Can anyone review it? Thank you so much! Glavo [1]: https://github.com/openjdk/jdk/pull/16556
