Will there be considerable gains from writing some sort of kernel module, vs. a userspace solution? I've never hacked the kernel or written any sort of kernel module before, but I'm eager to do so. What is the most low level API for this sort of thing, to avoid API overhead, if I should do it in user space? thanks, sh To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
