CLOUD PERFORMANCE TUNING
ASSIGNMENT- 10
Q1.) Write a program in java to get the maximum amount of memory (sandbox
limit) for a Java application
INPUT
public class spin{
private static long startTime;
private static void spin(int milliseconds)
{
long sleepTime = milliseconds*1000000L; // convert to nanoseconds long startTime =
System.nanoTime();
while ((System.nanoTime() - startTime) < sleepTime) {}
}
public static void main(String[] args)
{
final int NUM_TESTS = 1000;
long start = System.nanoTime();
for (int i = 0; i < NUM_TESTS; i+
+)
{
spin(500);
}
System.out.println("Took " + (System.nanoTime()-start)/1000000 + "ms (expected " +
(NUM_TESTS*500) + ")");
}
