Why SQL Server is slow?
Missing indexes, an inadequate storage I/O subsystem, or a slow network are only some of the possible reasons why a SQL Server database engine might slow down, which is why finding the true cause of a performance bottleneck is vital. … Poor index design. Poorly designed database schema. Inadequate storage I/O subsystem.
Is MongoDB faster than SQL?
