Java Sorting Performance

This page shows the result of the comparison between kvm, xen and host. The program contains 2 configration tasks. The first on sorts an ArrayList with a size of 10000 and the second one sorts an Vector with a size of 10000.

  • Java Version: Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
  • Command line: 
  taskset 1 java -jar JBench.jar jbench.properties

Results

  • Sol1 (Host):
    • Sort (ArrayList): Mean=29; variance=68
    • Sort (Vector)  : Mean=33; variance=7;


  • xmiguana (KVM Guest)
    • Sort (ArrayList): Mean=55; variance=1800; // 1 Processor
    • Sort (Vector)  : Mean=35; variance=7; // 1 Processor
    • Sort (ArrayList): Mean=76; variance=3990; // 2 Processors (without taskset)
    • Sort (Vector)  : Mean=36; variance=5; // 2 Processors (without taskset)
    • Sort (ArrayList): Mean=68; variance=5339; // 2 Processors (with taskset)
    • Sort (Vector)  : Mean=33; variance=0; // 2 Processors (with taskset)


  • Tokay (Xen Guest):
    • Sort (ArrayList): Mean=29; variance=0;
    • Sort (Vector): Mean=47; variance=2;
