Performance regression after JDK-8324241

XMLWordPrintable

      We noticed several timeouts with internal tests and -Xcomp after JDK-8324241 in JDK 23 b08. The performance regression also seems to affect serviceability/sa/ClhsdbDumpheap.java, see https://github.com/openjdk/jdk/pull/20237 for details.

      Before, and with -XX:-AlwaysRecordEvolDependencies, test execution time is between 15m 40s and 19m 13s.
      After, test execution time is between and 18m 28s - 24m 16s. This a regression of ~26%.
