If the JVM is in JITServer client mode, GCR counting will be enabled even during JIT startup phases (but not during JVM startup phase which only happens once). This allows GCR recompilations to happen sooner, improving rampup. In client mode there is a lesser risk that GCR recompilation overhead will impact the throughput of the JVM. This change can be overridden by using the following environment variable: export TR_LookAtJitStateForGCREnablement=1 Signed-off-by: Marius <mpirvu@ca.ibm.com>
