CAS CAS Performance Optimization and Troubleshooting

Question 1

Which technique is most effective for reducing application response time when database queries are the primary bottleneck in a CAS-certified application?

Accepted Answer

Implementing query result caching

Answer

Implementing query result caching reduces repeated database hits and significantly lowers response times when queries are the bottleneck.

Question 2

In CAS application troubleshooting, what does a high CPU utilization combined with low memory usage typically indicate?

Accepted Answer

Inefficient algorithms or compute-intensive processes

Answer

High CPU with low memory usage points to inefficient algorithms or tight loops that consume processor cycles without requiring large data buffers.

Question 3

Which load testing metric is most critical for establishing performance baselines in a CAS application deployment?

Accepted Answer

Number of concurrent users at peak throughput with acceptable response time

Answer

Concurrent users at peak throughput with acceptable response time defines the system's capacity boundary and is the core baseline metric.

Question 4

What is the purpose of profiling an application during CAS performance optimization?

Accepted Answer

To identify code hotspots consuming the most execution time

Answer

Profiling instruments the running application to pinpoint which functions or code paths consume the most CPU and memory resources.

Question 5

During CAS application troubleshooting, an error log shows repeated 'connection pool exhausted' messages. What is the most appropriate first step?

Accepted Answer

Increase the maximum connection pool size after analyzing current usage patterns

Answer

Analyzing current usage patterns first ensures the pool size increase is appropriate and rules out connection leaks before tuning the limit.
