Add sub-metrics for Event.Latency.TouchToFirstScrollUpdateSwapBegin |
|||
Issue descriptionWe defined a set of sub-metrics to measure the latencies inside Event.Latency.TouchToScrollUpdateSwapBegin to help us better understand the time spent on each stage during scroll. Now we will add the same set of sub-metrics to Event.Latency.TouchToFirstScrollUpdateSwapBegin. The details are in this doc: https://docs.google.com/document/d/1EPKT652e2PcO1ysA7LQosGyyr1xmxbtiiiivNU3lnpQ/edit#heading=h.r6af7ldx7kcw.
