Question: A key to the performance of the VSWS resident set
A key to the performance of the VSWS resident set management policy is the value of Q. Experience has shown that with a fixed value of Q for a process, there are considerable differences in page fault frequencies at various stages of execution. Furthermore, if a single value of Q is used for different processes, dramatically different frequencies of page faults occur. These differences strongly indicate that a mechanism that would dynamically adjust the value of Q during the lifetime of a process would improve the behavior of the algorithm. Suggest a simple mechanism for this purpose.
