Multi-tier Architecture Performance Issues Quiz

Performance Issues in Multi-Tier Architectures

• A common cause of performance issues is database bottlenecks.

Factors Affecting User-Perceived Performance

• Increasing throughput directly affects user-perceived performance.

Reducing Queue Lengths

• Increasing throughput can help reduce queue lengths in a multi-tier application.

Remedies for Database Bottlenecks

• Using a faster database is NOT a common remedy for database bottlenecks.

Asynchronous Processing

• Message queuing is a technique that improves performance by allowing asynchronous processing.

Load Testing

• The primary benefit of load testing is to identify performance bottlenecks in an application.

Common Reasons for Performance Issues

• Insufficient resources is NOT a common reason for performance issues in multi-tier applications.

Data Transfer Efficiency

• Data compression is a technique that improves efficiency by reducing duplicated data transfer.

Vertical Scaling

• Vertical scaling improves throughput in multi-tier architectures.

Performance Testing

• Load testing is a type of testing that verifies application performance under increasing user load.

Sustained High Load Testing

• Soak testing is a technique that verifies application behavior under sustained high load.

Caching

• Caching improves performance primarily by reducing the number of database queries.

Query Efficiency

• Increasing query efficiency reduces the time spent on database queries.

Database Optimization

• Database bottlenecks are often best addressed by optimization and indexing.
