| Memory Test Applet: This applet will try to allocate all memory available to your Java Runtime Environment (JRE). It is not an exact test, it is only a general indication of how much memory is available to an applet running in this browser on your computer. There may be long pauses while your computer system reorganizes it's memory allocations so be patient and wait for the test to finish. When the number turns GREEN then the test is finished and the GREEN number indicates how much memory an applet can use in this browser on your computer. |

How to adjust the JRE Memory: Open the Java Runtime Environment (JRE) control panel. The JRE control panel can be found in the Control Panel Folder -- Start –>Settings –>Control Panel –> Java. In the Java Control Panel, click on the Java tab. At the top you will see -- Java Applet Runtime Settings -- click the View button. You will see another dialog box titled -- Java Runtime Settings -- at the right of that dialog box you will see Java Runtime Parameters. Click below that title in the white text entry box. Copy and paste one of the following memory settings EXACTLY as it is typed below. They control how much memory Java can use at startup (-Xmsnm) and the maximum amount of memory to use (-Xmxnm). (n) the number in the middle, has to be a multple of 1024 such as 64, 128,196, 256, 512 etc. The trailing m means megabytes. You can use k but that means thousand bytes and that's too small. But each browser and computer will only allow certain maximum numbers so try the arguments below in accending order until either your browser crashes or Java won't load then back off one set of parameters. Your JRE will then have it's memory settings maximized. Memory Settings: -Xms64m -Xmx128m -Xms128m -Xmx196m -Xms128m -Xmx256m -Xms196m -Xmx256m -Xms256m -Xmx512m -Xms512m -Xmx768m The above parameters set the JRE available memory. You can enter any other reasonable number you want -- like 256 or 512 or any other even multiple of 1024 that is no greater than one fourth (¼) of real physical memory on your computer. The JRE currently has a bug that can limit an applet to use no more than one fourth (¼) of real physical memory on some computer systems. Questions: email support@pancyl.com |
