Answer

We would need a lot more information to be able to tell what's going on here.

* What exactly is "slow"?
* What does your CPU metrics look like?
* Do you have enough memory available on the EC2 server?
* Is it a networking issue causing the slowness?  Can you ping the server and get a decent response time?
