Hi

Could you please tell me the Linux server configuration for PM which has about 300 concurrent users.

You probably want to use one server with mysql. A NAS server to hold the /shared/ directory which holds the case files.

Then you can have two or three application servers where ProcessMaker is installed and use a reverse proxy server to direct the traffic to those 2-3 application servers.

You need to plan for 125MB of RAM per concurrent user in the application servers, plus 1 GB for the operating system.
NGINX is better than Apache.
