Last page insert contention is common in a busy SQL Server environment where multiple users are inserting data simultaneously in a table and that table has clustered index on a identity column. When multiple sessions try to add data in the same data page file, the data page becomes "hotspot". As a result, processes queue up to acquire access to the last page, which leads to latch contention, high wait times, and overall reduced performance. Understanding why last page insert contention arises and its mitigation techniques are crucial for handling workloads with rapid inserts.
