Unfortunately we don't have a very satisfying memory-based file system at this time. The last time I tried it (6 mo. ago), md(4) rushed pages out to the backing swap vs. being smarter about what to flush from the buffer cache. I was getting the same performance with a real FFS /tmp and a large amount of core. The malloc(9) mdmfs is always 100% core resident. -- -- David (obrien@FreeBSD.org) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
