There is a signficant design flaw that the buffer cache is synced into the MFS server, but that really doesn't have a severe performance hit. I plan to work on MFS in V3.1, but it isn't going to gain that much, because it isn't that bad to begin with. (That is the reason that I am not working on it now.) -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, and jdyson@nc.com | it irritates the pig.
