When reporting an LMS slow response issue, please provide the following details to expedite the troubleshooting process:

2.1 Steps to Reproduce:
  1. Provide detailed, step-by-step instructions on how to reproduce the slowness.
  2. Specify when the slowness typically occurs (e.g., during the initial login, after working in the system for a while).
  3. If the slowness is related to specific actions, include details about those actions, such as:
  4. Taking a course (specify if it's a regular course or a Rustici course.
  5. Running reports.
2.2 User and Occurrence Details:

  2. Date(s) and Time(s) the issue occurred.
  3. Exact steps the user(s) took when they encountered the slow response.
  4. User(s) location (e.g., city, country) and whether they are in the same or different locations.
  5. Browser type (e.g., Chrome, Edge).
  6. How the user(s) are connected to the internet (e.g., office network, home internet).

2.3 Scope of the Issue:
  1. Indicate if all users are affected or only specific users.

2.4 HAR File:
​
If possible, provide a HAR (HTTP Archive) file capturing the slow response. This file contains detailed information about the web browser's interaction with the LMS server and can be very helpful in diagnosing performance bottlenecks.

3. Generating a HAR File in Chrome or Edge

A HAR file can be generated using the developer tools in Chrome or Edge:

    1. Open Developer Tools:
  1. Launch Chrome or Edge and navigate to the page where you are experiencing the issue.
    1. Open Developer Tools by:
      1. Right-clicking anywhere on the page and selecting "Inspect".
      2. OR pressing F12 or Ctrl + Shift + I (Windows) / Cmd + Option + I (Mac).

  1. In Developer Tools, click on the "Network" tab.
    3. Check "Preserve log":
  1. Ensure the "Preserve log" checkbox is selected. This prevents the logs from being cleared when the page reloads
    4. Clear Existing Logs (Optional):
  1. Click the clear (⛔️) icon to clear any existing logs, if desired.

    5. Reproduce the Issue:
  1. Perform the actions that cause the slow response (e.g., click login, submit a form, launch a course).
    6. Export the HAR File:
  1. Click the download icon in the upper-left corner of the Network tab.
  2. Download the .har file.
  3. Save the .har file to your computer.

    7. Share the HAR File:
  1. Send the saved .har file to the support team for analysis.
