There is one other possibility. Typically the swap code is using compatibility disk I/O functions instead of the best the kernel can offer. I haven't looked recently but it might be worth just making certain that there isn't some low-level optimization or cleanup possible on that path. Although I may just be thinking of swapfiles. I know there were tremendous gains ago when I removed the functions that wrote pages synchronously to swapfiles.
