....code even if it has not been aggressively optimized. At the least, these miss ratios suggest that this workload requires a much larger BTB, and perhaps a different branch prediction method. Hilgendorf and Heim report that BTB miss rates improve for BTBs up to 16k entries for OLTP workloads [45]. Finally, we note that the speculative execution factor, or the number of macro instructions decoded divided by the macro instructions retired, is 1.4 for the overall system. The speculative execution factor for nearly all SPEC programs is between 1.0 and 1.3 [15] 3.5.3. Is out of order ....
