This page covers performance issues experienced on the web and application when the website loads with a delay.


SolarWinds NPM


This is because the Orion Server does not meet the minimum system recommended hardware requirements.


Add more System CPU, and make sure that your Orion server meets the minimum hardware requirements.

Hardware requirements for the latest NPM version

The following table lists minimum hardware requirements and recommendations for your SolarWinds server on physical computers, virtual computers, and cloud instances.

Use the minimum hardware configuration if you are evaluating the product or do not anticipate heavy usage.

SolarWinds strongly suggests using the recommended hardware configuration to avoid potential performance issues caused by a heavy load or custom configurations such as increased data retention or more frequent polling intervals.

Installing multiple SolarWindsOrion Platform products on the same computer may change the requirements.

Hardware requirements are listed by deployment size, based on the SolarWinds NPM license levels.

CPU recommendations for XL deployments use the PassMark Score. To learn more, see Pass Mark Performance Test (Copyright © 2018 PassMark® Software, obtained at on April 9, 2018).
