    • Affects Version/s: 12
    • Component/s: hotspot

      In the Graal version the hottest part is the temporary buffer clearing related to JDK-8207775 but that part is not as hot in the profile on C2.

      Run just this single micro with:

      java -jar jmh-jdk-microbenchmarks-1.0-SNAPSHOT.jar crypto.full.AESBench.decrypt -f 1 -wi 8 -p algorithm=AES/CBC/PKCS5Padding
