The big one is USB. disk/radio->kernel->user-space-usbd->kernel->application. Four copies. I would like to start playing with software defined radio on Plan 9, but that amount of data copying is going to put a lot of pressure on the kernel to keep up. UNIX/Linux suffers the same copy bloat, and it's having trouble keeping up, too. --lyndon
