If SolarWinds Support directed you to use a troubleshooting tool called Hubble (Turn on and use Hubble with Orion modules ), you may notice that the Other Time value is unusually high. The Other Time value is the remaining load time after database and Business Layer requests are complete. This includes SWIS, IIS and .Net Caches, and .Net object creation time.
There are several methods you can try to speed up the Orion Web Console website, as described in this article. Each item may or may not be applicable, but none of them will have a negative impact. 


Other time is the remaining load time after Database and Business Layer are complete. This will include SWIS connectivity, loading of IIS and .Net Caches, and .Net object creation time. 

 

Ruling It Out

• If Other time is quick, then the problem lies elsewhere:
  

In the example above, 159 ms for Other time is clearly not an issue

Proof Positive

• If in like the example below, Other time is high at over 85 seconds, the things that contribute to Other time is what you want to focus on
  
• High response times here may indicate old cache data or slow SWIS response time
• Check Orion.InformationService.log for long running queries
• Look for errors in Orion.InformationService.log
• Check for communication issues with other polling engines

Orion Platform

Large number of temp files and improper settings

Here's what you can do if Orion website performance is due to slow load times in Other time

The .NET cache needs to be cleared

• ​This is one of the first things you can try to reduce Other time
• See the Clear .Net cache manually  article for more information.
• Make sure to wait for 15-20 minutes before trying to launch the Orion website again to see if the load times have improved
• If clearing the .NET cache does not immediately fix the issue, see  the next section on website optimization

 

The website needs to be optimized

• You might need to run website optimization if clearing the .NET cache does not resolve the issue
• See the Website optimization for initial compilation and caching  article for more information.

 

Antivirus Exclusions

• The Antivirus software in the environment might be locking does certain folders Orion needs
• Make sure that the customer has the proper exclusion configured in their antivirus software
• See the Files and directories to exclude from antivirus scanning for Orion Platform products  article for more information.

 

Automatic update of root certificates

• If the items above still doesn't resolve the issue, try turning off automatic root certificate update on the Orion server
• It's possible that the Orion server is configured to update its root certificates over the Internet. If this fails for some other underlying reason, this might cause website performance issues
• If you see long running SWIS queries in OrionWeb.log and OrionInformationService.log, it is likely that this is causing the website performance issue
• You might also see cypt32 errors in Windows Event logs if this is the case
• See the Turn off automatic root certificates update  article for more information.

 

Folder Permission Issues

• Orion might not have the proper permissions to certain folders it needs
• You can use Check permissions using the Orion Permission Checker  to check and fix folder permission issues

Set server to prefer IPv4 over IPv6

• You may have problems connecting to websites that are participating in World IPv6 Launch, and you may either fail to connect to the website or you may experience a long delay before the website begins to load. Specifically you have IPv6 connectivity to the Internet, but it is not working properly. This can be caused by a computer or a router configuring Windows with IPv6 connectivity that is unreliable. 
• The Prefer IPv4 over IPv6 Fix it solution will configure your computer to prefer IPv4, instead of IPv6. By default, Windows prefers IPv6 over IPv4. If you are having problems using IPv6 to connect to some websites, this may resolve the problem.
• If you want to configure your computer to prefer IPv6 again, you can use the Prefer IPv6 over IPv4 Fix It.
• To use this fix, you must be logged on to the computer as a member of the Administrators group, or your user account must be granted permissions to edit the Windows registry
