      Description

      We've noticed a 3 - 5% regression with jetstream in mantis b02,
      b03 and b04 vs. Hopper FCS when run with -server on solaris sparc. The 'Read' subbenchmark has taken the biggest hit (~40%). Looking at flat profiles (-Xprof), it looks like it's spending more time in compiled code in mantis.

      Jetstream can be found here: /net/alacrity/export/local/ws/prod.install/workload/refWorkload/benchmarks/jetstream

      To run:

      java -server -Xmx256m -Xms256m JetStream -r 5

      -r <n>: number of times to run.
