= Using Red Hat Enterprise Linux for Real Time

|
If your workload has stringent low-latency determinism requirements for core kernel features such as interrupt handling and process scheduling in the microsecond (μs) range, you can use the {op-system-rt-kernel}. The goal of the {op-system-rtk} is consistent, low-latency determinism that offers predictable response times.

|
|
When considering system tuning, consider the following factors:
|
|
|
|
* System tuning is just as important when using the {op-system-rtk} as it is for the standard kernel.
|
|
* Installing the {op-system-rtk} on an untuned system running the standard kernel supplied as part of the RHEL 9 release is not likely to result in any noticeable benefit.
|
|
* Tuning the standard kernel yields 90% of possible latency gains.
|
|
* The {op-system-rtk} provides the last 10% of latency reduction required by the most demanding workloads.
