Increased timeouts can indeed lead to slower response times for users with fast connections.

I'm investigating the timeout issue we encountered during our Cube call. While I understand that timeouts are a maximum wait time, I'm interested in confirming if increased timeouts can still lead to slower response times for users with fast connections. My testing suggests they might.

Test Results:

Timeout ValueScenario 1 ResultScenario 2 Result60 secondsTimed OutTimed Out2 minutesFetched (63 seconds)Timed Out3 minutesFetched (63 seconds)Fetched (172 seconds)Observations:

Increasing the timeout resolved the issue for Scenario 1 but significantly slowed down Scenario 2 (109 seconds).

Questions & Insights:

My findings seem to align with potential downsides of high timeouts:

  1. Client-Side Timeouts: Even with a fast server response, client-side timeouts (e.g., web browser) can force users with fast connections to wait for the entire timeout duration.
  2. Unnecessary Delays: High timeouts might lead to:
    1. Retries or communication attempts: These can delay response for fast connections that wouldn't experience them with lower timeouts.
    2. Inefficient resource allocation: This can impact overall responsiveness for all users.
  3. Resource Allocation & Blocking:
    1. High timeouts can hold resources (threads, database connections) longer, creating a backlog for new requests (including those from fast connections).
  4. Error Detection & Recovery:
    1. Shorter timeouts allow for faster error detection and retries, improving user experience for fast connections.
    2. Longer timeouts can lead to delays before the system recognizes and addresses failures.
  5. Overall System Throughput & Latency:
    1. High timeouts can reduce the rate at which the system processes requests, impacting latency for all users.
    2. Optimized timeouts can improve overall system throughput and user experience.

Request & Confirmation:

Would you be able to share your insights on these potential downsides and how they might apply to our specific situation? Your analysis of the potential downsides of high timeouts is very insightful! To help us determine the optimal timeout settings for our situation, I'd appreciate your confirmation on the following:

  1. Client-Side Timeouts: Is it accurate that even with a fast server response, client-side timeouts can force users with fast connections to wait for the entire timeout duration?
  2. Unnecessary Delays with High Timeouts: Can high timeouts lead to unnecessary delays for users with fast connections due to retries, communication attempts, or resource allocation issues?
  3. Impact on Error Detection & Throughput: Do shorter timeouts allow for faster error detection and improve overall system throughput, benefiting users with fast connections?

Additionally:

If there are any reference documents or URLs that further support these concepts, I'd be grateful if you could share them. This would provide a more comprehensive understanding for our team.

Thank you for your time and expertise.

    Hello ***@Ashfaq Abdullah Lhi Provider Portal

    Here is a Solution of your issue:
    Certainly! Let’s delve into the implications of high timeouts and how they might relate to your specific situation: Client-Side Timeouts: Even with a fast server response, client-side timeouts (e.g., web browsers) can force users with fast connections to wait for the entire timeout duration. Consider adjusting timeouts based on the expected responsiveness of your application to avoid unnecessary delays for users. Unnecessary Delays: High timeouts may lead to: Retries or Communication Attempts: These can delay responses for fast connections that wouldn’t experience them with lower timeouts. Inefficient Resource Allocation: Impacting overall responsiveness for all users. Evaluate whether the benefits of longer timeouts outweigh the potential delays. Resource Allocation & Blocking: High timeouts can hold resources (threads, database connections) longer, creating a backlog for new requests (including those from fast connections). Optimize resource allocation to strike a balance between responsiveness and resource utilization. Error Detection & Recovery: Shorter timeouts allow for faster error detection and retries, improving user experience for fast connections. Longer timeouts can lead to delays before the system recognizes and addresses failures. Overall System Throughput & Latency: High timeouts can reduce the rate at which the system processes requests, impacting latency for all users. Consider fine-tuning timeouts to enhance overall system throughput and user experience.

    Hope this will solve your issue!!!

    Warm Regards
