 One method for handling latch contention is to replace a sequential index key with a nonsequential key to evenly distribute inserts across an index range. Typically, a leading column in the index distributes the workload proportionally. Another method to consider is table partitioning. Creating a hash partitioning scheme with a computed column on a partitioned table is a common approach for mitigating excessive latch contention. In the case of pagelatch IO contention, introducing indexes helps to mitigate this performance issue.
