Subject [jira] [Created] (S4-95) Add reproducible performance benchmarks

--------------------------------

             Summary: Add reproducible performance benchmarks
                 Key: S4-95
                 URL: https://issues.apache.org/jira/browse/S4-95
             Project: Apache S4
          Issue Type: Test
    Affects Versions: 0.6
            Reporter: Matthieu Morel


In order to track performance improvements, we need some reproducible performance benchmarks.
Here are some ideas of what we'd need:

- what is the maximum throughput without dropping messages, in a given host (in a setup with
1 adapter node and 1 or 2 app nodes)
- using a very simple app, with only 1 PE prototype
- varying the number of keys
- using a slightly more complex app (at least 2 communicating prototypes), in order to take
into account inter-PE communications and related optimizations

Some tests could be part of the test suite (by specifying a given option for those performance-related
tests). That would allow some tracking of the performance.

We could also add a simple injection mechanism that would work out of the box with the example
bundled with new S4 apps (through "s4 newApp" command).
