Real-time is not about performance, but about predictability ;) I have
to be sure that my flowgraph always executes before the deadline is
hit. So everything that introduces jitter is a no-no.
In general, Gnu Radio executes on general-purpose OSes, which means that
there will *always* be microsecond-to-milllisecond scale
jitter in executing code. If you want 100s-of-nanosecond to
microsecond scale execution timing predicability, Gnu Radio is going to
be the least of your worries, in my experience. The kernel can
prempt you at any time to deal with interrupts, etc.
