Does it stay there? What sort of processor utilization are we talking about?

My team and I spent the last few months putting together the DynDNS Spring Server VPS platform for folks needing IPv4 and IPv6 Linux servers on Xen. Would love feedback, both good and bad!
Lame server means that the domain doesn't have any dns footprint on the server for which it is requesting. But the lame servers queries don't take any cpu resources. As they cant make any request on the asked servers.
When nobody on the server I mean nobody is browsing a site, named is at the top and using too much resources?
nobody user mean that the file who requested something is not owned by him. When someone request a httpd connection, it goes to nobody user. Again, if some email send by sendmail without any header goes to nobody user owned process. And most of the requests on named and httpd should be nobody. Because most of the guys who will request for these kind of requests to the server will not be owned by him. But think like ftp, they have authorizations. Thats why there are so few process you will get which is owned by nobody running ftpd.
And about the top process, if you use "Top" command and named process comes at the top of the process list that doesn't mean it is taking the high resources. Top is a real time command, it updates in every second according to the top command configuration. But if the process comes in top that means when top tried to process the working reqested links, he find named process at first. Check other options of the named process on the top resulted command. you can get different informations of it, whether how much cpu load it is taking and memory usage etc etc.
And these will define whether it is the top process or not
