HeavyLoad is intended to stress all resources of a PC (like CPU, RAM, hard disk, network, operating system, etc.) in order to test if it will run reliably under heavy load. This is useful for assessing important file or database servers before using them productively, or just to check if your new PC might get too hot when used intensively.

HeavyLoad also allows to test the behavior of systems under fading system resources (memory, disk space).

Test Options:

Full CPU load

This test fully load the processor up to 100%. For this purpose HeavyLoad performs a complex calculation.

Write temp file

HeavyLoad creates a temp file to which it writes data continuously during the test. The data rate at which the test file will be written to disk can be specified in the options dialog.

Allocate Memory

HeavyLoad continuously allocates memory so that the system has less available memory. The data rate at which the memory will be allocated can be specified in the options.

Start TreeSize

This test starts for each local partition an instance of TreeSize Free. TreeSize Free will run in a continuous loop until the test is terminated.

Changelog:
• Redesigned user interface.
• HeavyLoad is now available as German version, too.
• HeavyLoad can now be executed with command line parameters.
• HeavyLoad can now allocate the complete physical memory on systems with more than 2GB memory.
• The chart now displays the free space of the system partition, too.
• The duration of the test can be set in the options dialog.
• The limitation for remaining disk capacity and memory can be defined.
• It is possible to set the speed in which the temporary test file is written and the memory is allocated.
• Added function to check for available updates.
• HeavyLoad now stores the user settings in an XML file in the user's profile.
• The support for Windows 2000 has been dropped because Microsoft dropped it in July 2010.
• Bugfix: The temporary test file can now be deleted in all situations.
• Bugfix: The temporary test file can now be written constantly even if the test option "allocate memory" is active. constantly even if the test option "allocate memory" is active.
• Bugfix: Now the free memory chart displays the correct value on systems with more than 4GB memory.
• A few minor bug fixes and improvements have been incorporated.
