• For RTI Connext DDS Micro: The binaries provided as part of the release are compiled statically against the RTI Connext DDS Micro 3.0.3 with the Security SDK libraries.

RTI Perftest 3.2

RTI Perftest 3.2 has been developed to add support for RTI Connext DDS Professional 6.1.0 while keeping the compatibility for previous releases. It also fixes a few bugs and erroneous behaviors found in previous versions. You can now test the huge performance improvements of using Data Compression, test your scenarios using the new UDPv4_WAN transport or understand the performance impact when using the extremely useful Network Capture feature.

What's New in 3.2

Support for Connext DDS Professional user data compression

RTI Perftest now supports (in the Traditional C++ API implementation) testing performance scenarios that enable the new compression feature introduced in Connext DDS 6.1.0.

Support for new WAN transport

RTI Perftest now supports testing the new WAN transport (in the Traditional C++ API Implementation). It can be accessed as a new -transport command-line option argument. See Use-Cases and Examples for an example of its usage.

Support for Connext DDS Professional's network capture feature

RTI Perftest added support in this version for the network capture capability, introduced in Connext DDS Professional 6.1.0 (in the Tradditional C++ API Implementation).

RTI Perftest Modern C++ API now compiles with C++11

The RTI Perftest Modern C++ API has been updated to require a C++11 compiler. The command-line option for the language passed to the rtiddsgen script is now C++11 instead of C++03.

What's Fixed in 3.2

• Warning message when using security and a custom governance file was sent to stdout

RTI Perftest 3.1

RTI Perftest 3.1 is focused on adding stability to the product, by addressing a lot of usability issues as well as fixing bugs and erroneous behaviors. Now you can extend RTI Perftest to work with other ecosystems, use more friendly output formats for visualization or comparison and perform tests using your own data as payload!

What's New

Use CSV or JSON as output formats

Perftest's new default output is in CSV, which enables the user to quickly generate graphs, compare between runs or integrate the tool with testing environments. This is not the only new output format, as JSON is also available as an output format. The custom legacy format is also available to maintain compatibility.

New tutorial section in the documentation

There is a new section in the documentation featuring tutorials on how to use Perftest to gather performance numbers in different scenarios. Right now it is populated with an article explaining the first steps needed to measure Latency and Throughput between two Linux nodes. New articles will be added in the future.

Find the tutorials page here.

Use Perftest with custom payloads

Perftest now enables the user to send actual data as the payload of the samples sent to test the latency and throughput. A new option has been added to the Traditional C++ API implementation that allows you to load a file into memory and send the data of the file instead of using an empty buffer as the payload for the RTI Perftest messages.

Extend and use Perftest for other Middlewares

Perftest Traditional C++ API implementation has been improved. The class dependencies have been cleaned up, as well as the file layout. A new implementation for Semaphores, timers, clocks, etc is now available to avoid the dependencies with the RTI Connext DDS middleware.

A new section in the documentation explains this in detail.

RTI Perftest 3.0

What's New

RTI Perftest is packed of new features, the most remarkable ones are:

Support for custom types: Use your own types in RTI Perftest (#33)

Now RTI Perftest allows you to easily use your own types. See this document to see how to start using them.

Thread priorities can be configured via command-line parameter (#65)

Setting the internal RTI Connext DDS thread priorities can be really useful in order to fine tune your performance and achieve more stable latency and throughput results. This is especially important for Real-Time OSs. Now it can be done via a command line parameter in RTI Perftest

Raw Transport Support (Send directly via UDPv4 sockets or via Shared Memory and skip RTPS or DDS) (#77)

This feature can be key when trying to understand the maximum performance of a system: By using the -rawTransport option, you will be able to send directly via sockets (if you are using UDPv4) or via shared memory segments (if you are using SHMEM), skipping the RTPS and DDS protocols, but still using RTI Connext DDS for the serialization/deserialization. Read more about this here.

Support for RTI Connext DDS Micro 3.0.0 (#78)

Starting with this release, we introduce the ability to compile RTI Perftest against RTI Connext DDS Micro, this will allow comparing the achievable performance by both middlewares in the same scenarios.

Take into account that some of the features might not be available (yet) for RTI Connext DDS Micro.

Support RTI Connext DDS 6.0.0 FlatData and Zero-Copy features (#211)

Starting in RTI Connext DDS Professional 6.0.0, 2 key new features were introduced: Flat-Data and Zero-Copy. RTI Perftest now allows you to easily test these 2 new features and find how much gain can be achieved by its use.
