So if it's using one core, 25% would mean it's eating up all of one core's worth of CPU time (although it may or may not stay on that core).
However, if it's a threaded Xeon, that's 4 physical cores and 8 virtual cores, so 12.5% would be one core/one thread's worth of CPU time.
So it's possible that Wireshark is using an entire thread for one core, and is CPU-bound.
