The Telemetry 3 run-time has extremely low overhead, so profiling with Telemetry won't kill your program's performance. Telemetry gets out of the way when not in use, but is easy to turn on when you need it. Inactive (for example, when it's uninitialized, can't connect to a server, or is missing its DLL). Telemetry consumes very little overhead during normal operation, and even less when it's Telemetry is designed to be available at all times, not just when you're profiling. Shifting gears between "developing" and "optimizing" is disruptive,Įspecially when you have to change build settings and run your software differently. The best tools are the ones that you actually use, and for this reason Telemetry is designed to be "always on". Too many enemies, lights, AI pathing nodes, sound sources, particles, and so on are causing a dip in performance, Telemetry's visualization makes it glaringly obvious to everyone! Now everyone can work on performance independently- no more dragging a coder to an artist's desk just to point out that the particle spawner is emitting too many particles! Always On Whole Team ParticipationĪll this high level visualization means that the whole team, not just programmers, can contribute to optimization! Artists, designers, and testers can now correlate state with performance. Helps you discern patterns within your program's performance profile, which leads to more and better opportunities for optimization at a higher level. Modern software performance is incredibly complex, and optimization is no longer just about making one function faster. Music players, chat programs, etc.) preempt your program! On Windows, you can even see when other processes (virus scanners, updaters, Telemetry can show you context switches- see when threads migrate betweenĬores (Windows & PS4) and when threads are swapped in and out by the scheduler. What else was going on in my system? Telemetry offers additionalįorensic information to help you get to the bottom of performance issues.
Now you can see when one thread is interfering with another! Why is this thread slow? Telemetry has programmer-driven profiling, where you mark up the code for precision profiling,Īs well as sample-based profiling, where you sample a threads callstack periodically and then organize the results. How are my threads behaving? Telemetry shows you the relationship between your own threads: lockĬontention, stalls, starvation, and idle areas are all presented visually. When something bad happens is just as important as knowing
hitches and hiccups) so that you can isolate the circumstances of poor performance. Shows you those spikes in frame time (i.e. Most profilers tell you that something was slow, but they usually can't tell you when things got slow.
