Hello, for some of my workloads I'm seeing high ILD_STALL.ANY counter values - ~20% of total unhalted CPU cycles (.THREAD). And ~95% of these stalls come from ILD_STALL.IQ_FULL, whereas ILD_STALL.LCP is all zeroes. I seem to fail to find any info on how harmful ILD stalls are when the instruction queue is full (it does not sound half as harmful as "instruction queue is empty" would :) ), and I'm curious how to interpret these high counter values - what is the performance problem they are signalling me about and which other counters can confirm the diagnosis? I'm running on a NHM processor. Thanks!
