Workaround:

FileCloud uses background workers to process messages being written to the database. By default, in a multi-tenant environment, each tenant is assigned 4 workers. If the CPU is not able to handle this number of workers, performance will be degraded due to high CPU usage.  

This can be fixed by changing the worker configuration in the configuration file to use global workers. 

File Path:
Linux: /var/www/html/src/Scripts/config/default.json
Windows: xampp\htdocs\src\Scripts\config\default.json

To configure background workers to global mode, change the global_worker parameter to true and restart fcorchestrator service. This will limit the total worker limit to 4, which will be shared across all tenants. 

To restart the service:
Windows : Use FileCloud Control Panel or Windows Services
Linux: service fcorchestrator restart or systemctl restart fcorchestrator
