Example 1 with TLongLongHashMap

use of gnu.trove.TLongLongHashMap in project intellij-community by JetBrains.

the class CpuUsageData method measureCpuUsage.

public static <E extends Throwable> CpuUsageData measureCpuUsage(ThrowableRunnable<E> runnable) throws E {
    FreeMemorySnapshot memStart = new FreeMemorySnapshot();

    for (GarbageCollectorMXBean bean : ourGcBeans) {
        gcTimes.put(bean, bean.getCollectionTime());
    }
    TLongLongHashMap threadTimes = new TLongLongHashMap();
    for (long id : ourThreadMXBean.getAllThreadIds()) {
        threadTimes.put(id, ourThreadMXBean.getThreadUserTime(id));
    }
    long compStart = ourCompilationMXBean.getTotalCompilationTime();
    long start = System.currentTimeMillis();
    runnable.run();
    long duration = System.currentTimeMillis() - start;
