Database Performance Testing Areas

Query Performance: Individual query execution time
Concurrent Connections: Multiple simultaneous connections
Data Volume: Large dataset performance
Index Performance: Index usage and effectiveness
Transaction Performance: ACID compliance under load
Backup and Recovery: Data integrity and speed
