MRG Realtime

For the most time-critical workloads, "close enough" isn't good enough. For instance, in the highly competitive financial services marketplace, milliseconds make the difference between a trade and a lost customer. In these environments, consistently fast response times are a huge competitive advantage.

MRG Realtime provides the highest levels of predictability for consistent low-latency response times to meet the needs of time sensitive workloads. For most customers, a properly tuned standard Red Hat Enterprise Linux system provides acceptable levels of determinism.

For applications with extremely demanding latency requirements, MRG Realtime provides new levels of determinism by optimizing lengthy kernel codepaths to ensure that they do not become bottlenecks. This allows for better prioritization of applications, resulting in consistent, predictable response times for high-priority applications.

This chart illustrates the latency over time of a third-party messaging system run on two different servers. The red line plots the messaging software's latency on standard Red Hat Enterprise Linux 5 out of the box. And the green line shows the same messaging software's latency when running on Red Hat Enterprise Linux 5 with the MRG Realtime kernel installed. As this chart shows, the MRG Realtime kernel significantly improves the determinism of this messaging application.
