WebinarUpcoming Webinar: Know What’s Changed – with NEW Server Configuration Monitor

Change management in IT is critical. But, even with a good change management process, changes are too often not correctly tracked, if at all. The configuration of your servers and applications is a key factor in their performance, availability, and security. Many incidents can be tracked back to an authorized (and sometimes unauthorized) configuration change, whether to a system file, configuration file, or Windows® Registry entry. Join SolarWinds VP of product management Brandon Shopp to discover how the new SolarWinds® Server Configuration Monitor is designed to help you.

Since upgrading to NPM 12 and NTA 4.2, the Orion web performance has noticably slowed down.


  • NPM 12.x and NTA 4.2


In somecases, antivirus software is causing this issue.


  1. Either disable/uninstall the antivirus software from the system, or exclude c:\programdata\solarwinds and c:\program files (x86)\solarwinds from AV.
  2. Re-run the configuration wizard.
