If I have two domains pointing to the same machine, but one resolves to an internal address and the other to my internet facing router, will there be any differnce in route taken to my machine (primarily in terms of performanc).

eg.

internal.mydomain.com resolves to 192.168.1.200 
external.mydomain.com resolves to A.Web.External.IP

both eventually resolve back to the same machine. For a client in the network, will using the external address give a performance penalty?
