RadPerf running in another server.

Hello, I'm currently running FreeRADIUS 3.0.4 on a CentOS server and I wanted to use RadPerf for testing. Since I cannot install RadPerf in CentOS, I installed RadPerf in a separate Ubuntu 14.04 server, my question is: which is better for RadPerf installation? on the same server where FreeRADIUS was installed or different server?
