    I open-sourced my book about SW performance. All the source Markdown, images, and Latex files are now open. Anyone can easily build a PDF version. This book now belongs to the whole community. I invite everyone to contribute to it. github.com/dendibakh/perf… 1/3

    It has been a long journey! After almost a year of work the first draft of my book about performance analysis and tuning is ready.🎉 I know many people are struggling these days so I decided to make the book FREE. I'm looking for people who would like to review the book. (1/2)

    I wanted to write about Intel Processor Trace for a long time. This is a revolutionary way of doing performance analysis which creates many opportunities that were unavailable before. Here it is, enjoy! :) easyperf.net/blog/2019/08/2… #performance #IamIntel

    I spent a large amount of time last year working on optimizations that try to improve layout of machine code. I decided to write a blog post about what it is and show some basic types of such transformations. dendibakh.github.io/blog/2019/03/2…

    I wrote a beginner-friendly post about performance analysis of multi-threaded applications. This is a short introduction on metrics and tools that will help you understand performance of your MT app better. easyperf.net/blog/2019/10/0… #perf #performance #multithreaded #IamIntel

    I wrote an article showing how one can measure precise timing (in cycles) for basic blocks in the program using Linux Perf. dendibakh.github.io/blog/2019/04/0… #perf #performance #LBR #CPU

    Compilers are known for doing all sorts of cool optimizations. What about your CPUs itself? I wrote a small blog post about it. dendibakh.github.io/blog/2018/04/2… #performance #CPU

    There are many HW and SW features that increase performance, but bring non-deterministic behavior. I wrote an article how to deal with non-determinism in Linux and get consistent benchmarking results. easyperf.net/blog/2019/08/0… #perf #performance #linux #cpu

    I see people are often misleaded by looking at CPU performance counters when doing analysis (me no exception). I wrote a short article about how not to fall into this trap. easyperf.net/blog/2019/07/2… #perf #performance #iamintel
