Hi,

Following is my farm environment running on Hper-V.

2 App Server
2 Web Server in NLB,, 01 server RAM 24 GB, 02 server RAM 16 GB
1 Search Server
3 Workflow Manager server in NLB
02 SQL Server 2012 

Problem which we are facing is high memory utilization, memory utilization goes upto 98% and sharepoint stop responding services and secondly 01 web server getting more request as compare to second webserver.

Please guide me make best utilization of RAM  and Web Server NLB.

Thanks

• On what servers is AppFabric running?
• Where is Workflow Manager 1.0 installed?
• What is your search topology (what components are installed on which server)?

Hi,

Distributed Cache service running on Application server 2 and webserver 2.

For workflow manager i have created 3 node workflow cluster.

For search i have dedicated single server for search.

Web -01 :  94% memory utilization

Web -02 : 74% memory utilization

Thanks

Hi,

To know more about this performance issue, we need to capture verbose log, fiddler log for SharePoint.

Unfortunately, forum support has limited support and resources regarding debugging request, if you would like to debug, I recommend you to submit a case to our premier support where our engineer can remote help you directly.

Thanks for your understanding and support.

Best regards,

Victoria

Hi,

To ensure a well performing farm see if the below data points are matching:

• User load is not more than 5000 ( In case of larger user load a dedicated Distributed Cache server is recommended)
• Its better to distribute the search components across 2 application servers.
• Ensure NodeRunner.exe(search component) is not running on the web front ends.
• Continuous Crawl has to be used carefully for only critical applications
• Also, Secure Store Service application can be another critical resource consumer incase of mysites feature being enabled.

Monitoring the above, could help you to narrow down on the bottleneck.

You haven't told us the top consuming processes from task manager, so everyone is guessing at the source of the problem. Can you please share what the top processes are in terms of their private working set are?

Hi,

IIS worker process are top consuming process, there are many process are running.

thx

Okay, great.

Run:

C:\Windows\System32\inetsrv\appcmd.exe list wp

That will allow you to translate the PID of the highest memory usage w3wp to the name of the Application Pool as it is displayed in IIS. My assumption is that it will be an Application Pool that hosts one or more SharePoint Web Applications.

Hi,

command return following results now what have to do, pls guide.

C:\Windows\System32\inetsrv>appcmd.exe list wp
WP "2184" (applicationPool:d61e4bc635584b68b722dc7a2d2257c6)
WP "9220" (applicationPool:SPAppPool2)
WP "11524" (applicationPool:SPAppPool1)
WP "11560" (applicationPool:SPAppPool3)
WP "4752" (applicationPool:SecurityTokenServiceApplicationPool)

thx
