I have 190MB of mfs, fstab entry of which is as follows: swap /tmp mfs rw,-s=380000 0 0 Recently (since the end of last year, I guess) I noticed that when mounting mfs, heavy disk I/O occurs. It seems that mfs's VM space is swapped (or paged) out when it is invoked (or when mfs newfs'es its VM space). Could it be because of an mfs implementation change? VM? Any ideas? -- Takanori "Roy" Saneto To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
