Alto uso de CPU observado por el proveedor WMI "deploymentprovider", que forma parte de ServerManager.DeploymentProvider.dll

Question

Estoy usando PowerShell Desired State Configuration para probar/configurar las funciones de Windows en la máquina del servidor. Lo que tengo son 78 recursos de WindowsFeature para verificar e instalar si es necesario. Lo que observé es un uso elevado de la CPU mientras LCM (Administrador de configuración local) ejecuta y verifica la configuración. Investigué un poco y descubrí que el proveedor WMI "deploymentprovider", que es parte de ServerManager.DeploymentProvider.dll responsable del recurso WindowsFeature, es la causa. Entonces la pregunta es, ¿alguien ha experimentado este problema y lo ha resuelto de alguna manera?

Gracias de antemano.

Answer 1

78 WindowsFeaturerecursos es mucho. Puede intentar consolidar las comprobaciones utilizando un Scriptrecurso y escribiendo el código usted mismo (o creando un recurso personalizado). La mayor parte del tiempo de CPU invertido probablemente sea una sobrecarga, por lo que si verifica los 78 a la vez, debería ser mucho más rápido.

Aquí está mi código y los resultados finales de la prueba. El ejemplo de búsqueda tarda aproximadamente 80 veces más en probar los recursos. Por lo tanto, vale la pena mantener la cantidad de recursos al nivel mínimo y manejar todo dentro de su código.
