+// e32test/defrag/perf/t_perf.cpp
+// t_pagemove loads and opens the logical device driver ("D_PAGEMOVE.LDD").
+// Following this, it requests that the driver attempt to move various kinds of pages
+// directly amd notes time taken for each of the moves.
+// Platforms/Drives/Compatibility:
+// Hardware only. No defrag support on emulator.
+// 2 - Test the performance of moving user chunk pages
+// 3 - Test the performance of moving dll pages
+// 4 - Test the performance of moving kernel stack pages
