On some machines that do routing and have a full view in the kernel I do this is in /boot/loader.conf: kern.vm.kmem.size="128000000" # Sets the size of kernel memory (bytes) But this is not very optimal because only half of the kernel memory can be used for the routing table. The other half (64MB here) is mostly empty. I'l like to know if there is a way to adjust this ratio in the kernel so I get 96MB for the routing table and 32MB for the kernel itself. -- Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
