Yes, but without the mount_mfs process kludge it seems to allow for single copy, rather than double copy and extra context switches, it uses kvm instead of a user process for backing store. My question, can/will this ever be backed by swap? Also, doesn't this limit us to just kvm memory (much smaller than total memory) ? -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
