Executive Summary: HIS Transaction Integrator Performance

This is a summary of the Microsoft Host Integration Server Transaction Integrator Performance white paper. Click here to download the full document.

Respectable mainframe transaction throughput numbers range from approximately 220 transactions per second (TPS) to 350 TPS on a single host. (The IBM cluster (parallel sysplex) claims high throughput rates of 770 TPS.)

Microsoft® Host Integration Server 2006 (HIS 2006) offers faster transaction response times for .NET Transaction Integrator (.NET TI), compared to previously published statistics of its predecessors. While the Microsoft BizTalk® Adapter for Host Applications was not offered in previous versions, the test results for this adapter are impressive, based on transactional throughput. It can be concluded that HIS 2006 TI can benefit any organization looking to leverage .NET TI as an enterprise-level integration solution.

Summary of Performance Tests

The following table displays a summary of the data collected for Host Integration Server Transaction Integrator 2006 on a Dual-Core AMD Opteron Processor 2220 SE 2.81 GHz, with a brief description of the test. These tests and specific data regarding their implementation and relevance are detailed later in this white paper.

Notes:

  • Heavy data conversion includes all possible data types.
  • Medium data conversion includes 1/3 char, 1/3 float, and 1/3 packed decimals.
  • Light data conversion includes character data type only.
  • User-defined data types (UDTs) and Microsoft ActiveX® Data Objects (ADO) disconnected record sets handle structured data.
  • Unit of Work (UOW) time is the time allocated for host transaction processing. (Also referred to as host response time or host processing time.)
  • REOverride enables the application to select the Customer Information Control System (CICS) Remote Environment (RE) at the time of executing each transaction.
