Continuing with our Performance Tuning series as you have learned baselining and knowing your normal system performance metrics is an important part of performance tuning. In part 1 we discussed collecting vital system metrics such as CPU Utilization and Memory usage. In part 2 we took a glimpse into how we can gather those metrics and other using the different tools that are available to use like Performance Monitor, Profiler, Extended Events and DMVs. In this part 3 we will look at how identifying the appropriate waits events and corresponding resolution will be critical for resolving performance issues. But first you need to understand what waits are and where to find…
