what to do when swf respondDecisionTaskCompleted call, response time degrade overtime

What steps should I take if the swf respondDecisionTaskCompleted call response time degrades over time?

If the respondDecisionTaskCompleted call in Amazon SWF is experiencing degraded response times over time, consider the following steps:

Monitor Performance: Track the performance metrics of your SWF workflows to identify patterns or bottlenecks.

Optimize Workflow Decisions: Ensure that the decisions made within your workflow are efficient and do not introduce unnecessary delays.

Check Resource Utilization: Monitor the resource utilization of the systems running your SWF deciders and workers. High CPU or memory usage can impact performance.

Review Network Latency: Investigate any network latency issues that might be affecting the response times.

Update SDKs and Libraries: Ensure that you are using the latest versions of the AWS SDKs and libraries, as updates often include performance improvements and bug fixes.

Implement Caching: Use caching mechanisms to store frequently accessed data, reducing the need for repeated data retrieval operations.
