com.oracle.graal.hotspot.test.MemoryUsageBenchmark

public class MemoryUsageBenchmark
extends HotSpotGraalCompilerTest

Used to benchmark memory usage during Graal compilation. To benchmark:

     mx vm -XX:-UseJVMCIClassLoader -cp @com.oracle.graal.hotspot.test com.oracle.graal.hotspot.test.MemoryUsageBenchmark
 

Memory analysis for a CompileTheWorld execution can also be performed. For example:

     mx --vm server vm -XX:-UseJVMCIClassLoader -G:CompileTheWorldClasspath=$HOME/SPECjvm2008/SPECjvm2008.jar -cp @com.oracle.graal.hotspot.test com.oracle.graal.hotspot.test.MemoryUsageBenchmark
