Loadperf The Loadperf component provides the base functionality necessary to install and uninstall extensible performance counter dynamic-link libraries (DLLs). It is used when performance counters need to be exposed.

This component contains the following files:

  • Loadperf.dll. This is the helper .dll file that manipulates the performance registry.
  • Lodctr.exe and Unlodctr.exe. These executable files are command-line tools which load and unload extension performance counter DLLs.
  • Perfc009.dat and Perfh009.dat. These file system files reflect the current state of the performance registry.
  • Perfd009.dat and Perfi009.dat. These file system files reflect the initial state of the performance registry.

Loadperf.dll can be used to install or remove extension performance counter DLLs, back up or restore the performance registry, and update system base performance counters.

Perfc009.dat and Perfh009.dat reflect the counters that have been installed on the system since the operating system was installed, while Perfd009.dat and Perfi009.dat contain only the counters that were initially installed during the installation of the operating system.
