event ECh probe miss means what

Discussion created by jiayaocang on Dec 2, 2007
event ECh is probe responses, as i kown to maintain cache coherence, once cache miss, other caches should be probed, so could i conclude that one cache miss incurs many probes and many probe responses? as a example, in 4-way smp , one cache miss will produce 3 probe to other processors' cache.
