A significant advantage of the 64-bit kernel is that the processor can make use of more registers. In addition to ease of virtualization, an advantage of 32-bit userland, is that code is smaller, so that cache is used more efficiently. -- Joel Roth _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
