Description
It was found that llm_bench shows very low throughput for speculative decode. This happens because llm_bench calculates the latency for tokens other than the first based on the
PerfMetricsraw_metrics.m_new_token_times, which do not take into account the batch.raw_metrics.m_durationsare also calculated based onraw_metrics.m_new_token_times, but the time is divided into batches, which significantly affects the calculations for speculative decoding.CVS-174513
