VM Validator

VM Validator allows the virtual memory behaviour of an application to be monitored. As virtual memory is consumed, memory is paged out from physical memory to disk storage, and memory is paged in to physical memory from disk storage.

VM Validator allows you to examine which pages are physically present in memory and thus gain a better understanding of your application's virtual memory usage. Typically, the more paging behaviour, the worse the performance (in speed terms) of the application. By analysing which parts of your application cause the behaviour monitored by VM Validator you can determine which parts of the application can benefit from different memory allocation algorithms and different memory access algorithms.
