:I have 128MB of memory and 700MB of swap area on my PC. : :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 <URL:mailto:sanewo@ba2.so-net.ne.jp> 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 <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
