The overhead of fixing/unfixing a page is trivial. Once a page is fixed it should stay fixed. The overhead of paging is non-trivial. Looping through code that fixes and unfixes pages won't show anything useful. I suspect the only way to truly measure the overhead (or benefit) is to create non-page fixed buffers and then run that way for a week. Change to fixed buffers and run for another week. Compare the results.
