Application Profiling and Tuning – Or How I Stopped Worrying and Learned to Love the Tweak


“Any sufficiently advanced technology is indistinguishable from magic.” - Arthur C. Clarke, Clarke’s Third Law Problem solving and troubleshooting is an art. An art of science. Most people have some knowledge and intuition around problem solving, but very few have the right methodologies and tools to do it right. This lab teaches abstract, scientific methods to profiling applications and improving their behavior, stability and performance – with Linux, of course. Using software from our favorite operating system - strace, lsof, perf, to name a few - you will learn how to detect, isolate, analyse and fix every kind of problem that comes your way. Whether you're facing potato farm crop issues, spaceship performance or just plain-ole IT woes, this lab has it all. Participants should have some knowledge of Linux and/or programming. Participants may wish to bring their own laptops to the workshop.
