A processing node tracks probe activity level associated with its cache. The processing node and/or processing system further predicts an idle duration. If the probe activity level increases above a threshold probe activity level, and the idle duration prediction is above a threshold idle duration threshold, the processing node flushes its cache to prevent probes to the cache. If the probe activity level is above the threshold probe activity level but the predicted idle duration is too short, the performance state of the processing node is increased above its current performance state to provide enhanced performance capability in responding to the probe requests.
