How do you identify database performance problems?
Types of performance issues to look for
- Application slowdowns. The most important indication of potential database performance issues is when things that used to run fast begin to run slower.
- System outages. When a system is down, database performance obviously is at its worst.
- The need for frequent hardware upgrades.
What is a database issue?

What are some of the most common database problems?
Common Database Problems 1 Slow Read-Write Speeds. Performance slowdowns can occur due to high latency for disk read/writes. 2 Scaling Problems. Trying to scale up a database isn’t necessarily a straightforward operation. 3 Incorrect Virtual Machine Setup. 4 Lack of Backup and Monitoring.
