The answer is, unfortunately, "it depends".
For example, I'm running a very simple radio astronomy "flow" on an Odroid XU3 at 2 x 11.5Msps,without overruns (except occasionally).
What type of computer are you using? Have you made certain that any filters you have in your flow don't have horrendous filter lengths?
That's very often a cause of newcomers getting poor performance out of their signal flows. They specify a filter with far-too-aggressive
"skirts", which yields a filter that is 10 times longer than it really needs to be, for example.
