Async Processing Benchmarks

Create a ravendb database on a sevrer with high latency from you, such as in the AWS when running the benchmark from your computer.

Add database information to appsettings.json or create an appsettings.local.json

Seed database with Sample data. This is available in the UI with RavenDB 4

Compile the project for Release, and run.
