Title:

The surprising realities of tuning the WebSphere Liberty profile.

Stream:

WebSphere Application Server 2 (3)

Speakers:

Abstract:

More threads, if only we had more threads, why doesn't Liberty create more threads? This was the starting point for a week-long discussion around tuning the performance of the WebSphere Liberty profile in order to achieve the right throughput for a system. The default assumption being made was that more threads, and more JDBC connections were needed to achieve the required throughput, when the exact opposite was true.

Why was it that the counter intuitive decision that fewer threads was better? During this session Alasdair will explain this and more. Come along to gain important insights in how to get the best performance from the WebSphere Liberty profile. As an added benefit much of the information is also applicable for WebSphere Application Server full profile.
