The genuine perfmon.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation. "PerfMon.exe" should be found in "C:\Windows\System32". It is Microsoft's "Resource (or "Reliability") and Performance Monitor". Its user interface (GUI) harnesses the underlying ability of Windows, Windows Server, SQL Server, and other software systems to accumulate detailed statistics about how quickly and efficiently CPU cores, physical and logical disk drives, network interfaces, and other aspects of the hardware and software are operating. Built into these systems is a structure of named "processes", (e.g., "Memory", "Physical Disk", "Process"), each having named counters, (e.g., "Memory\Available MBytes"), which PerfMon can activate to capture data at varying time intervals, viewing it in real time or accumulating log files. "Data Collectors" can be defined, using XML, standardizing what processes and counters are tracked, for re-use or export. PerfMon can be run against other computers accessible through a network. Related command-line programs named "logman.exe", "relog.exe", and "typeperf.exe" enhance PerfMon's ability to collect and report this information.

It's the performance monitor, but why it needs acess to the internet I can't tell. Brunn
It is the most resource hungry process running on my netbook.
Yes, it is a file name for the performance monitor. It should not run all the time if the performance monitor is not running. I checked this out on my laptop and desktop. The laptop that is running very slow has this process running without the performance monitor open. This tells me I need to look at where this file is located. If it is not located in the right place I think it should be removed. Christopher
Windows program trust full but in some computers jack up cpu usage to 100% Te.name
why do you need a performance monitor as the system runs at the it own level anyway the perfmon.exe in that was is useless and is out dated my idea MS is to get rid of the junk stay with the better plan simple fast and fluid techienumber1

Best practices for resolving perfmon issues
A clean and tidy computer is the key requirement for avoiding problems with perfmon. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
