The only swap issue I have is with Firefox on FreeBSD desktop with
less than 12gb RAM. ie, 8gb machine will start paging eventually. This
could be an issue that was solved though, I think I remember people
complaining about FF. But when FF starts paging the easiest is to
reboot. Yes, it has to do with hella tabs open after a month or so. :)
FreeBSD servers are running 32gb or 64gb RAM and those have not been
paging. That i've noticed.
