Linux Performance

This page links to various Linux performance material I’ve created, including the tools maps on the right. The first is a hi-res version combining observability, static performance tuning, and perf-tools/bcc (see discussion). The remainder were designed for use in slide decks and have larger fonts and arrows, and show: Linux observability tools, Linux benchmarking tools, Linux tuning tools, and Linux sar. Tools perf_events: perf one-liners, examples, visualizations. eBPF tools: eBPF tracing tools and examples with bcc. perf-tools: perf analysis tools using ftrace (github). bcc: perf analysis tools using eBPF (github). ktap: one-liners, examples, and scripts. Flame Graphs: using perf, SystemTap, and ktap. For more information, see: http://www.brendangregg.com/linuxperf.html
