Clearmem

//Myth// - "Running Clearmem improves performance by freeing up memory."

//Reality// – "Microsoft's Clearmem, the memory-consuming test tool, is a simulation tool that lets developers measure the minimum working set for a process and to help system administrators isolate cache bottlenecks on servers. Clearmem was originally found on the Windows NT Resource Kit 4.0 CD and can now be found on the Windows Server 2003 Resource Kit. It allocates and references all available memory, consuming any inactive pages in the working sets of all processes (including the cache) and effectively clears the cache of all file data. As Clearmem increases its working set the working sets of all other processes are trimmed until they contain only pages currently being used and those most recently accessed. This reduces the performance of all running applications every time you run this by reducing their amount of available memory, forcing them to needlessly page and causing any cached file data to have to be reread from disk."
