已识别原因

Missing or Inefficient Indexes

90%

Lack of appropriate database indexes on frequently queried columns forces the database to perform full table scans, significantly slowing down query execution.

Unoptimized SQL Queries

80%

Queries may be poorly written, using subqueries unnecessarily, selecting more columns than needed, or performing complex operations that could be simplified.

N+1 Query Problem

75%

This occurs when an application makes one query to retrieve a list of items, and then for each item, it makes a separate query to retrieve related data, leading to a large number of inefficient queries.

Large Data Sets and Inefficient Joins

65%

Joining very large tables without proper indexing or efficient join strategies can lead to significant performance bottlenecks.
