Add Benchmark to Track Connector Performance over Time

It would be nice if we had a set of benchmarks that we could use to track improvements and regressions in the performance of each connector over time. Ideally, these benchmarks would be in a separate module so that we would not have to run the benchmarks every time that we built the project. Better still would be if we automatically captured an "official" benchmark run as part of the release process and stored the results in a file across releases.
