Description
This advanced training course is meticulously crafted to equip IT professionals with the practical knowledge and technical depth required to excel in the Red Hat EX442 Performance Tuning Exam. Participants will engage with a curriculum that directly aligns with the core objectives of the exam, encompassing system-level diagnostics, kernel and memory tuning, storage and network performance optimization, and fine-grained resource control through systemd and cgroup configurations.Each module integrates hands-on labs and real-world scenarios that simulate performance challenges commonly encountered in enterprise Linux environments. Through these exercises, learners gain exposure to tools such as sar, valgrind, tuned, and sysctl, enabling them to analyze bottlenecks, debug system behavior, and optimize workloads for both bare-metal and virtual deployments.The course also emphasizes strategic tuning methodologies for CPU scheduling, I/O throughput, NUMA awareness, and memory allocation — critical factors in enhancing application responsiveness and system stability. Learners will apply proactive diagnostic techniques, troubleshoot anomalies, and make data-driven adjustments across diverse infrastructure layers.By the end of the program, participants will have honed a performance-first mindset and built the confidence to manage high-demand workloads, solve complex system performance issues, and successfully validate their skills in preparation for the EX442 certification — a mark of excellence in Red Hat enterprise system optimization.
