#General performance metrics.

Given a Datablox application, we want to measure the following:

1. _Is the performance of Datablox acceptable for the application?_ Examples: if the throughput of the bookmarks app is the same as the crawl-rate, then the framework is not adding any appreciable overheads to the process. Click's main experimental result was that it could pass on packets at the maximum rate which can be processed by the Linux kernel. While a monolithic router could go at a faster rate, it is irrelevant as it will not make any difference to the system.

2. _How does it scale?_ Does adding more machines help scale linearly? At what point does adding more machines not help the system? What are the minimum number of machines needed for the throughput to be acceptable for the application?

3. _How reusable are the blocks?_ Certainly every application will have something specific to it, but what is its proportion to the rest of the application code?
