Upgrading the new environment to make use of appfabric cache. This is a cache that exists between the sql server and the main server.
It's generally easy to scale out the web servers but not the database server (without switching to a nosql solution). This reduces the load on the database significantly by placing it on a scalable cache.
It also should have the side effect of some code taking fractions of a second instead of minutes, but that's not the real intent (in fact, it's O.K. if it slows down some stuff) - the idea is to have a constant response time on the servers regardless if there is one user on or ten thousand users on.
