Hi @jddarcy ,
Test has been modified on the same lines using generic options which manipulate
compilation thresholds and agnostic to target platforms.
* @run main/othervm -XX:Tier3CompileThreshold=100
-XX:CompileThresholdScaling=0.01 -XX:+TieredCompilation RoundTests
Verified that RoundTests::test* methods gets compiled by c2.
Test execution time with and without change is almost same ~7.80sec over
Skylake-server.
