 I have observed a single match for that instruction, so it must be the init, and there were only 20k instructions after it, so the impact is negligible.
+* gem5 simulates memory latencies. So I think that the CPU loops idle while waiting for memory, and counts will be higher.
 
 This works because we have already done the following with QEMU:
