Lower Latency

Respond more rapidly to changing market conditions and business needs and maximize your revenue opportunities.

If your firm can respond more quickly to new information and changing market conditions, you have a distinct advantage over those that cannot. Running your time- sensitive mission-critical applications using SUSE Linux Enterprise Real Time Extension reduces process dispatch latencies, and gives you the time advantage you need to make more money or avoid further financial losses, ahead of your competitors.

The Real Time Extension achieves these lower latencies with a preemptible real-time kernel, together with the ability to identify which specific application threads are high priority processes. The incorporation of high resolution timers in the real time kernel allows for more fine grained measurement of time slices, further enabling lower latency.

Greater predictability

Ensure critical business processes complete in time, each and every time, and deliver high quality of service, even under heavy system loads.

Timing is everything. In some cases, predictability of response times is even more important than absolute speed. Even more important than how fast it takes for a process or application thread to execute, is making sure that it takes the exact same time to complete, each and every time.

Certain process control applications, computer simulations, and high performance risk management algorithms require the precise synchronization of intermediate execution threads in order for the system as a whole to function properly. You can get better performance from these time sensitive applications, through greater predictability, when you use SUSE Linux Enterprise Real Time Extension.

The ability of SUSE Linux Enterprise Real Time Extension to shield or "reserve" key system resources for high priority processes, together with its preemptible real time kernel, is what ensures greater predictability of your time-sensitive mission-critical applications. You can be confident that your time-critical applications do not experience resource contention, or unwanted process interrupts that could contribute to increased variability in response and execution times.

Service Pack 1 includes enhancements to the real-time scheduler and locking mechanisms, which enhance performance while maintaining predictability. The spinlocks in SUSE Linux Enterprise Real Time Extension have been modified to reduce operating system context switching times, dramatically improving the performance of throughput sensitive workloads.
