1. If you notice the above MB (megabyte) estimate changes slowly and erratically, it usually indicates that this computer's memory is overallocated (which forces the computer to use the much slower hard disk). If this is consistently a problem then lower size of the Java Heap Memory if you can, otherwise it is probably worth considering the purchase of more RAM memory for this computer.
  2. The actual heap memory defined for this computer may be significantly larger than the above results if other Java programs have been used by the browser. In which case, a more accurate result can be obtained by exiting all browser windows, then open a fresh copy of your browser and rerun this test.
