Why would you want RAM to be free?
try top(1).

"man ftpd" explains pretty much everything you need to know about
runnign anonymous FTP with the base system ftp daemon.  It isn't
capable of bandwidth shaping, although dummynet(4) is (in my opinion)
the best way to control that -- assuming you really need to, which
probably isn't the case, even if you think you do.  

I don't think the stock ftpd can control number of users.
