## Performance
Median small message throughput measured using the Throughput example between two Intel(R) Xeon(R)
CPU E3-1270 V2 @ 3.50GHz (that's 2012 hardware ...) running Linux 3.8.13-rt14.20.el6rt.x86_64,
connected via a quiet GbE and when using gcc-6.2.0 for a RelWithDebInfo build is:
![Throughput](https://raw.githubusercontent.com/eclipse-cyclonedds/cyclonedds/assets/performance/throughput-polling.png)
This is with the subscriber in polling mode. Listener mode is marginally slower; using a waitset the
message rate for minimal size messages drops to 600k sample/s in synchronous delivery mode and about
750k samples/s in asynchronous delivery mode. The configuration is an out-of-the-box configuration,
tweaked only to increase the high-water mark for the reliability window on the writer side. For
details, see the scripts in the ``performance`` directory and the [data](https://raw.githubusercontent.com/eclipse-cyclonedds/cyclonedds/assets/performance/throughput.txt).
There is some data on roundtrip latency below.

The number above were measure on Mac running a 4,2 GHz Intel Core i7 on December 12th 2018. From these number you can see how the roundtrip is incredibly stable and the minimal latency is now down to 17 micro-seconds (used to be 25 micro-seconds) on this HW.
