Agree. Heightened swapout in this rather simplified example) isn't a problem in itself, unless it really turns out to be a bottleneck in a wide variety of loads. As long as the *right* pages are being swapped and don't have to be paged right back in again.
I'll try a more varied set of tests tonight, with cpu usage tabulated.
