 IBM® WebSphere® MQ Low Latency Messaging is a messaging transport that is highly optimized for the very high-volume, low-latency requirements of Financial Markets firms. Applications include the high-speed delivery of market data, transactional data, reference data, and event data in or between front-, middle-, and back-office. Although initially designed to meet the high-speed and throughput requirements of financial services firms, WebSphere MQ Low Latency Messaging is suitable for use by other industries with similar requirements. Characteristic applications require extremely low (submillisecond) latency and high message volumes (ranging from many thousands to millions of messages per second), with positive or negative acknowledgement reliability, but not requiring the assured delivery provided by WebSphere MQ. Performance characteristics On common x86 servers, WebSphere MQ Low Latency Messaging can deliver: - Approximately one million 120-byte messages per second on Ethernet
- Close to three million 120-byte messages per second on InfiniBand
- More than 8 million smaller messages (< 120-bytes) per second
- Very low latency of 30 microseconds for 120 byte messages delivered at 10,000 messages per second on InfiniBand
- Low latency of 61 microseconds for 120 byte messages delivered at 10,000 messages per second on Ethernet
The stated performance numbers are based on measurements using standard IBM benchmarks in a controlled environment. The actual throughput that any application will experience may vary depending upon considerations such as message size, transmission rate, hardware platform, and network configuration. Therefore, no assurance can be given that an individual application will achieve the throughput or latency stated here. Customers should conduct their own testing.
