Performance Monitor (known as System Monitor in Windows 9x, Windows 2000, and Windows XP) is a system monitoring program introduced in Windows NT 3.1. It monitors various activities on a computer such as CPU or memory usage. This type of application may be used to determine the cause of problems on a local or remote computer by measuring ...
Hardware performance counter. 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 ...
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] Userspace controlling utility, named perf, is accessed from the command line and provides a number of subcommands; it is capable of statistical ...
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
In computer science, Performance Application Programming Interface (PAPI) is a portable interface (in the form of a library) to hardware performance counters on modern microprocessors. It is being widely used to collect low level performance metrics (e.g. instruction counts, clock cycles, cache misses) of computer systems running UNIX / Linux ...
This method is different from many other methods using performance counters because all the cores in multi core processors are considered, the performance counters being used do not individually have high effect with power consumption and it estimates the power consumption for each core that can be used for real time scheduling of each core to ...
Resource Monitor, a utility in Windows Vista and later, displays information about the use of hardware (CPU, memory, disk, and network) and software (file handles and modules) resources in real time. [1] Users can launch Resource Monitor by executing resmon.exe (perfmon.exe in Windows Vista). The Vista and later Resource Monitor heavily ...
