Package Summary
Generates statistical data providing a benchmark for rpc messaging latencies.

Overview
This package includes two separate tests. Both tests effectively timestamp an rpc service message, sends to a server, which again timestamps the respons and sends it back. Upon receipt, latencies are calculated. The only difference between the two tests are the storage type - either integers or floats. This is important as on some embedded boards, float types can have some problems and also show a marked slowdown depending on whether it is software emulated or not.
Usage
Integral
roscd eros_rpc_latency/bin ./server ./client // in a separate terminal
Latencies will be printed every second, and upon termination of the client (ctrl-c), the average latency will be printed to standard output.
Float
roscd eros_rpc_latency/bin ./float_server ./float_client // in a separate terminal
