dialogflow cx v3 java library SessionsClient.detectIntend method: significant delays (over 3s)

[soonq]

Each time SessionsClient.detectIntent in the Dialogflow CX v3 library is executed, it encounters significant delays (over 3 seconds).

After creating a SessionsClient and configuring it to maintain sessions for 24 hours, I attempted to save the generated sessionsClient object itself or convert it to JSON and store it in Redis for reuse, but failedto do so.

Is there a way to store or reuse a SessionsClient created in a Java environment?

Alternatively, if there's a method to reduce the latency to within 1 second, I'd appreciate it.

For latency issues, there is no exact solution for this as it might come from various sources. I would suggest to follow these best practices in DialogFlow CX to help avoid high latency.

Thank you for your response. I'm encountering the following error when trying to convert SessionsClient to JSON for reuse. Can you suggest a solution?
