Thanks Junoyoon.. I will set my agents two cores and 4 GB RAM.

1.  My understanding is nGrinder controller doesn't require very powerful machines and only agents require more power full machines depending on the load. Is my undersdtanding correct?..
==> Right. controller doesn't need a powerful machine. When I run a test, it requires only 2~5% cpu load, It can be run with very limited machine like... 1 core, 2GB ram.

2. Do I need to improve the server configuration, if I plan to add many agents in future?..
==> 1 core, 2GB ram machine may handles more than 20 agents. Don't worry.

3. Is it possible to run multiple agents in single machine?.. ( If I have box of 4 CPU's and 8GB RAM, can I run 2 agents?.. )  .. My assumption is No.. Please correct me..
==> Yes.. if you set the NGRINDER_AGENT_HOME env var per each agent, you can run multiple agent...  or run the agents with different account.

==> However, it's not recommended.. 

==> Because this can cause the agent performance unpredictable.. 

Thanks Again..
