> bq. *Note: this ticket has become a ticket about improving the performance of
> the platform*
> In order to track performance improvements, we need some reproducible
> performance benchmarks. Here are some ideas of what we'd need:
> - use PEs that do nothing but create a new message and forward. Allows us to
> focus on the overhead of the platform
> - 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)
> - what is the latency for end to end processing (avg, median, etc...)
> - 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
> - start measurements after a warmup phase
> 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).
