Low-Level Linux  takes you beneath abstractions and frameworks and into the machinery that actually runs your software.\u003c\/p\u003e\n\n\u003cp\u003eThis book is a practical, deeply technical guide to how Linux works  from the metal up  — from virtual memory and page tables to syscalls, scheduling, and performance tuning at scale.\u003c\/p\u003e\n\n\u003cp\u003eWhether you’re optimizing high-throughput systems, debugging impossible latency spikes, or preparing for kernel-level work, this book gives you the mental models used by elite systems engineers.\u003c\/p\u003e\n\n\u003cp\u003eYou will learn how Linux  really  behaves under load — not just how it’s supposed to.\u003c\/p\u003e\n\n\u003cp\u003eInside you’ll master: How Linux virtual memory actually works\u003cbr\u003e\n(paging, MMUs, TLBs, NUMA, and page faults demystified)\u003c\/p\u003e\n\n\u003cp\u003eThe full syscall lifecycle\u003cbr\u003e\nfrom user space → kernel → hardware → back again\u003c\/p\u003e\n\n\u003cp\u003eHow context switching, scheduling, and interrupts impact latency\u003c\/p\u003e\n\n\u003cp\u003eMemory allocation internals\u003cbr\u003e\n(slab, slub, vmalloc, brk, mmap)\u003c\/p\u003e\n\n\u003cp\u003eCPU caches, false sharing, and cache-line–level optimization\u003c\/p\u003e\n\n\u003cp\u003eDiagnosing real performance problems using\u003cbr\u003e\nperf, ftrace, strace, bcc, and eBPF\u003c\/p\u003e\n\n\u003cp\u003eWhy “fast code” is often slow — and how to prove it\u003c\/p\u003e\n\n\u003cp\u003eHow to reason about performance using first principles, not guesswork\u003c\/p\u003e\n\n\u003cp\u003eWho this book is for: Software engineers ready to go beyond frameworks\u003c\/p\u003e\n\n\u003cp\u003eLinux users who want to understand what their system is truly doing\u003c\/p\u003e\n\n\u003cp\u003eBackend, infrastructure, and systems engineers\u003c\/p\u003e\n\n\u003cp\u003ePerformance engineers and SREs\u003c\/p\u003e\n\n\u003cp\u003eAnyone who wants to think like the kernel does\u003c\/p\u003e\n\n\u003cp\u003eNo fluff.
