Linux Kernel Performance and Optimization Questions

Covers deeper system performance analysis and optimization on Linux hosts. Topics include kernel level concepts such as process scheduling, memory management, and input output subsystems and how they impact application performance; identifying resource contention and bottlenecks; using profiling and tracing methodologies to collect evidence; safely tuning kernel and system parameters; optimizing CPU, memory, and disk input output for particular workloads; container and cgroup considerations; and capacity planning. Interviewers expect a clear diagnosis workflow, trade off reasoning, and practical tuning examples.
