Linux Virtual Memory and Large Page Support for Beginners

Modern software demands efficient memory management, yet standard page sizes can create significant performance bottlenecks in memory-intensive applications. Understanding how the operating system handles virtual memory is key to unlocking better system efficiency. This text-based course guides you through the foundational concepts of memory virtualization and shows you how to leverage large pages to optimize performance. You will learn how to configure, manage, and verify large page configurations on a Linux system. What you will learn: Understand the core principles of virtual memory, page tables, and Translation Lookaside Buffers (TLB). Identify how standard page sizes contribute to TLB misses and memory overhead. Configure and manage Hugepages and Transparent Hugepages (THP) in Linux. Monitor memory usage and verify large page utilization using standard command-line tools. Apply memory optimization strategies to database workloads and high-performance applications. The course begins with essential terminology and the mechanics of virtual memory before walking you through hands-on configuration steps and monitoring techniques. This course is designed for system administrators, developers, and Linux enthusiasts who want to optimize system performance, with no prior memory management experience required.
