Virtual memory allows offering to processes more memory than that physically available in the system, using a disc as a memory extension. When there is not enough RAM memory to satisfy the processes, the system becomes slow, because it spends the time doing paging, characterizing memory thrashing. This paper presents an evaluation of some commodity operating systems under thrashing. A portable benchmark tool was developed to bring each system to a thrashing and then back to normality. We also identify the performance data available in each system and the mechanisms available to collect them.
