I wrote a virtual motor controller in python for the EPICS Training at

Argonne in 2015:

  https://github.com/kmpeters/VirtualMotorController

This has a few advantages over the simulated motors included in the

motor module:

* the python script can be killed to simulate a controller failure
* the code can be easily modified to simulate bad behavior in the future

Hi Gedare,
The EPICS Core development and application development are different, although they are related of course.
It seems that as the first step, you want to focus on the application side, therefore some soft IOC and simulators like areaDetector simulator would be a good start.
You can definitely use simDetector to test your network performance, which gives you a reasonable frame per second depending on your server.
Another advantage of simDetector is that it supports both CA and PVA, therefore you can test both CA and PVA performance.

For the IO testing, unless you want to use some real hardware, you can use simulators which could give you same responses like your hardware.
It is fairly easy to develop one if you are using asyn for your hardware IOC. We have some preliminary hardware simulators at APS for our ASYN based IOCs.
Of course, virtual accelerator is also one of nice tool for your evaluation.

Thanks,
Guobao
