I am currently monitoring the memory usage of a newly installed Sharepoint Server. Since the server is new it only has 5 active users and 2 libraries with 5 documents.

The server has only Sharepoint running on it and is configured with 8 gb RAM. 83% of the RAM is used and mainly because of the Sharepoint Search component:

Sharepoint search

Is this normal behaviour or can tune some settings to resolve this?

There are some information about this behaviour. See here and here.

You can change e.G. the Performance Levels for your crawls.

Powershell Cmdlet:

Get-SPEnterpriseSearchService | Set-SPEnterpriseSearchService –PerformanceLevel "PartlyReduced"

For the setting to take effect do an IISReset or restart the Search Service in Central Admin

Performance Level Explained:

Reduced:

Total number of threads = number of processors, Max Threads/host = number of processors

PartlyReduced:

Total number of threads = 4 times the number of processors , Max Threads/host = 16 times the number of processors

Maximum:

Total number of threads = 4 times the number of processors , Max Threads/host = 16 times the number of processors (threads are created at HIGH priority)

Change noderunner.exe:

You can also edit the noderunner.exe config file located at:

C:\Program Files\Microsoft Office Servers\15.0\Search\Runtime\1.0\noderunner.exe

And set a value for <nodeRunnerSettings memoryLimitMegabytes="0" />

The zero means "unlimited" here. The only thing to do is to set to the amount of RAM you'd like to set as a limit for each noderunner.exe processes.

NOTE: Be aware, these settings might make your crawling processes slower.

Hope this will help a little.

    It's worth pointing out that the search service consuming a lot of memory is expected out of the box if none of these settings have been changed. – shufler Jan 25 '16 at 21:50

8 GB is way below the minimum for a standalone SharePoint server in production.

See this Technet Article.

After you "solve" this issue you will face many more until you add RAM and resources.
