Ensemble HL7v2 Performance & Scalability

Executive Summary

InterSystems Ensemble® is a rapid integration and development platform with built-in capabilities for high-speed processing of HL7 messages. It has been ranked as the #1 or #2 Interface Engine in healthcare every year since 2006 by KLAS, a prominent healthcare IT analyst organization based in the United States.

InterSystems recently completed a performance and scalability benchmark of Ensemble version 2010.2 (Maintenance Release 1), focusing on Health Level 7 version 2 (HL7v2)messaging. This document describes the observed characteristics, and also provides general configuration and sizing guidelines for systems where Ensemble is used as an interface engine for HL7v2 messaging.

The benchmark simulates workloads that have been designed to closely match live environments. The details of the simulation are described in the Workload Description and Methodology section. The tested workloads were comprised of HL7v2 Patient Administration (ADT) and Observation Result (ORU) payloads, and included transformations and re-routing.
