Describe your problem

Hi,

I encountered a performance issue when using the Q&A chatbot with an agent workflow.

Environment

• Number of documents: 16
• Workflow: Agent + Q&A chatbot
• Reranker top_k: 30
• Max rounds: default
• Retry times: default

Problem

The response time is very slow.
Even though the knowledge base only contains 16 documents, the chatbot sometimes takes a very long time to generate an answer.

Configuration

• Reranker top_k: 30
• Max rounds: default value
• Retry: default value

Question

1. Is top_k = 30 too large for a small knowledge base like this?
2. Could the agent workflow cause additional latency during retrieval or reasoning?
3. Are there recommended settings for small document collections to improve response speed?

Any suggestions for optimizing the response time would be greatly appreciated.

Thanks!
