But I am sure that you have that much disk space which you can allocate to swap, if not you already couldn't build it. And tmpfs swapping is still likely faster than a persistent FS (it will not need to block on syncs). If you are benchmarking, it is likely worth you effort since that will probably mark the upper performance bound,
