Performance profiler (sampled or instrumented) and analyzer, focused on game development. Proprietary Systemtap: Linux Programmable system tracing/probing tool; may be scripted to generate time- or performance-counter- or function-based profiles of the kernel and/or its userspace. Open source Valgrind: Linux, macOS, Solaris, Android
perf (sometimes called perf_events [1] or perf tools, originally Performance Counters for Linux, PCL) [2] is a performance analyzing tool in Linux, available from Linux kernel version 2.6.31 in 2009. [3]
In computers, hardware performance counters (HPC), [1] or hardware counters are a set of special-purpose registers built into modern microprocessors to store the counts of hardware-related activities within computer systems. Advanced users often rely on those counters to conduct low-level performance analysis or tuning.
As performance is part of the specification of a program – a program that is unusably slow is not fit for purpose: a video game with 60 Hz (frames-per-second) is acceptable, but 6 frames-per-second is unacceptably choppy – performance is a consideration from the start, to ensure that the system is able to deliver sufficient performance, and ...
The number of function points would be exactly the same, but aspects of the application would be different. The lines of code needed to develop the application would certainly not be the same. As a consequence, the amount of effort required to develop the application would be different (hours per function point).
Provider Count is the number of providers registered with the Windows Filtering Platform. Windows Time Service Windows Time Service Performance Counters display the time synchronization runtime information from the service. Note that the service has to be running in order for this information to be displayed.
To get better CPI values without pipelining, the number of execution units must be greater than the number of stages. For example, with six executions units, six new instructions are fetched in stage 1 only after the six previous instructions finish at stage 5, therefore on average the number of clock cycles it takes to execute an instruction ...
Performance engineering within systems engineering encompasses the set of roles, skills, activities, practices, tools, and deliverables applied at every phase of the systems development life cycle which ensures that a solution will be designed, implemented, and operationally supported to meet the performance requirements defined for the solution.
