VM? : :Any ideas? :-- :Takanori "Roy" Saneto There haven't been any changes specific to making it swap on startup. I've got a 300MB MFS partition and haven't noticed any heavy disk activity on startup. You could try reducing the number of pages mount_mfs touches when it newfs's the filesystem by specifying a higher bytes/inode ratio and playing with other insundry options. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
