When an applet runs on your machine by default there is an upper limit set on the amount of memory the applet can use, this will typically be around 96 MB. By increasing the memory allocated to the applet, 'ChopChop' will upload larger files taking less time.

To add additional memory, we recommend you follow these instructions:

  • Close all browser windows.
  • On the Windows XP Operating system, click on the Start Button, followed by Control Panel. On Windows Vista or Windows 7, this is found on the Classic View of the Control Panel. On the Mac OS X, the Java Plugin Settings icon is in a folder by navigating: Machintosh HD desktop icon -> Applications -> Utilities -> Java.
  • Open the Control Panel and look out for the Java plug in icon. You may have multiple Java Plugin icons on your Control Panel, select the one with version number being greater or equal to 1.6.0. You can find out the version number by clicking on the icon, followed by the 'About' tab.
  • To increase the amount of memory allocated to the applet, click on the Java tab. Under Java Applet Runtime Settings, click on the View button, you will get a window similar to the one shown below. In the text input field titled 'Java Runtime Parameters', fill in -Xmx150m and click on the Apply button. Here you are allocating 150 MB of memory. More memory can be allocated in similar fashion by replacing 150MB with a higher number. As a guide, this can be up to 50% of total RAM. For example, if you have 1 Gig of RAM, you could allocate 512MB of RAM and type in -Xmx512m.
