Software Dynamics: optimization of software performance. Saitits R.L.

Software - starting with mobile and cloud applications, ending with video games and autonomous transport management systems - is becoming more and more limited in time. It should provide reliable results smoothly, consistently and almost instantly. The inability to guarantee this will lead to consumer discontent, and in some cases can even create a risk to human lives. When the complex software works poorly or fails, engineers need to identify and fix the root causes. The task is not easy, and there were not so many tools to solve it. Richard L. Sail, an expert on performance analysis, solves the problem directly, offering effective methods and professional tools to identify the dynamics of complex, limited programs of programs, as well as to increase reliability and eliminate performance problems.

behind the author’s shoulders Several decades of practical work and training of professional developers. He introduces the reader to the principles and techniques that are applicable in any environment, starting with built-in devices and ending with the data centers, and reinforces them with examples based on the Ethernet systems of the X86 and ARM under the control of Linux. Based on the information received using Kutrace, readers will be able to use specific solutions, and not just sort out techniques, such as turning off the cache or nuclei.
