# SUSE Linux Enterprise Real Time Reviews **Vendor:** SUSE **Category:** [Operating Systems](https://www.g2.com/categories/operating-system) **Average Rating:** 4.3/5.0 **Total Reviews:** 36 ## About SUSE Linux Enterprise Real Time Whether it’s an IoT sensor monitoring industrial devices or an edge system that must act instantly on external inputs, SUSE Linux Enterprise Real Time is a real time operating system designed to reduce latency and increase the predictability and reliability of time-sensitive, business-critical applications. Banks, manufacturers, government agencies and others rely on time-dependent applications which must execute accurately and predictably all the time, every time. Precision Timing To act as a single unit, distributed systems need time accuracy not only within a server but across all servers. The Precision Time Protocol (PTP) synchronizes servers via the high-speed network, up to sub-microsecond accuracy. Predictability Includes support for device interrupt threads, enabling tuning at the device level, and hardware latency detectors to ensure predictability of application behavior. Low Latency SUSE Linux Enterprise Real Time gives you the time advantage you need to beat the competition. A fully preemptible real-time kernel allows you to specify which processes take priority over previously uninterruptible operating system processes, such as spinlocks and hardware and software interrupts. ## SUSE Linux Enterprise Real Time Pros & Cons **What users like:** - Users commend the **exceptional speed and low latency** of SUSE Linux Enterprise Real Time, crucial for time-sensitive applications.
