Well, you have to understand what you're testing.

With a test like this, you're really testing two different things:

1. How fast your database is,

2. How fast your frontend is

Since the query is simple, your frontend is basically a DB access layer and should be taking no time. And since the table is indexed the query should also take no time.

The only other interesting question is if the database can handle the number of connections and the storage is. The app is using connection pools, but the actual size of the database machine is never mentioned...which is a problem. How big is the DB instance? A small instance could be crushed with 80 connections. A database on a hard drive may not be able to handle the load either (though since the data volume is small, it could be that everything ends up cached anyway).

So this is sort of interesting, but sort of not interesting.
