ThingWorx Server CPU Usage increases with number of Users

[bmdeshmukh18]

Hello,

I have noticed that the CPU utilization of ThingWorx server is rapidly increasing with the number of users accessing the ThingWorx Runtime sessions. Although the CPU resources utilized by the system is comparatively smaller %.
What are the options using which we can reduces this % CPU usage. Is there any way to identify what is causing this higher CPU usage.
What may be the probable reasons for this.

Any help is appreciated.

Thanks & Regards,
Bhushan

You can do thread dumps using the Support Subsystem and analyze what is going on.

Also if it is truly user related, run the UI with developer tools and see what services are firing and if any are 'long running' or perhaps services are run repeatedly and try to mitigate those.
