The descriptors are parsed at Context start so the issue isn't how quickly Tomcat can find the descriptor file but how quickly Tomcat can map the request to the right Context. For the full details look in org.apache.catalina.mapper The short version is that Tomcat performs a binary search through an order list of context paths to find a match so, yes, it will be quick.
