hardware utilization and memory bandwidth, while reducing memory, cache, and peripheral access latency, thereby significantly improving application performance on Kunpeng servers. WayCa Scheduler offers hardware clusters and NUMA nodes. This fully utilizes L3 cache and memory resources, reducing system latency and improving throughput. • Furthermore, WayCa Scheduler provides user-mode topology support, which Cloud Native 017 openEuler OS Technical White Paper Innovation Projects Virt SIG HybridSched Low resource utilization of cloud data centers is a common issue in the industry, and has fueled ways to

In the event of OOM, memory reclamation is preferentially performed for process groups with low priorities to ensure the normal running of online services. Optimized mremap performance: Entries performance of file system functions (create, unlink, mkdir, rmdir). EulerFS delivers much shorter latency and higher bandwidth over EXT4 and DAX alternatives. Feature Description • Hash table directory: inodes. These operations become persistent in asynchronous mode to reduce the metadata operation latency. Application Scenarios EulerFS is perfectly suited to compliment new media, such as NVDIMMs. It

The cilium-etcd-operator will not take any measures packet into the ipvlan slave device of the other network namespace and therefore may achieve be�er latency results.
