DNS Caching Server

So this morning I setup an old pc as a CentOS DNS caching server, then set the other pc's at my apartment to use that machine as their primary dns server... Either I'm just imagining things, or doing this made a big difference in web site request response time. I should set the machine up to be a proxy server as well to also cache web content, then my internet connection will seem uber fast!

Has anyone else noticed an improvement when switching from your ISP's dns to a local dns cache?

you really shouldn't see such a difference here, and in theory the solution will slow things down when you go to new sites. a dns server should respond back within less than 100ms max, and that would include those ISP name servers forwarding on to other root servers etc if need be.
