noderunner.exe is eating all your memory?

Just as a note to myself: if you have to work with sharepoint you might notice a very high memory consumption from several noderunner.exe-processes.

There alerady exists an explanation of how to reduce this, here are the crucial steps:

• Open a Sharepoint Management Shell
• Set-SPEnterpriseSearchService -PerformanceLevel Reduced
• Get-SPEnterpriseSearchService
  Should show "Performance Level: Reduced" now
• Open C:\Program Files\Microsoft Office Servers\15.0\Search\Runtime\1.0\noderunner.exe.config in Notepad
• Update <nodeRunnerSettings memoryLimitMegabytes=”0″ /> to say 100
• Restart SharePoint Search Host Controller Service

And you are done.
