    Hi

    FreeBSD 4.9 man tunefs(8) explains in section "-m minfree" that default
    8% disk space is reserved for root. The man page also says clearly that
    I'll lose performance if I lower minfree.
    On my mailserver I've one drive for the base system and a raid
    enviroment with 500GB space for the users mailboxes. 8% of 500gb space
    is a lot of space which I can't use anymore for my users mailboxes.
    So if I set this minfree to < 8% is there any other option I've to set
    that I don't lose too much performance. We talk about a lot of write
    procedures for small files.

    Regards
    Thomas Vogt
