[Michael Musgrove]

Hello,

The Narayana team are proud to announce the latest release of Narayana!

course and when it is a nightly build of WildFly that includes the upgrade
will be available over here:

The commit is:
https://github.com/wildfly/wildfly/pull/12833/commits/bc6fcabf524a56e0d0d4c351c11ea3f65238b851

As is now normal, in this release we compared ourselves against four other
leading open source competitor products with a view to checking that the
release remains competitive. Results are produced using JMH (a micro
benchmark harness created by the OpenJDK project team available from
http://openjdk.java.net/projects/code-tools/jmh/). We have attempted to
configure each product on an equal footing by choosing sensible defaults
for each tunable parameter and by ensuring that recovery is enabled,
although we do configure narayana with the journal store, which is our best
performing transaction log storage mechanism. If you have any
recommendations for other transaction managers or how to tune the
configuration then please let us know so that we can update our test job.
The benchmark runs a transaction containing two dummy resources.

We will let the TPS (transactions per second) figures speak for themselves,
suffice to say that when more and more threads are thrown at the workload
we scale better showing that we have excellent control over parallelism.
