We are running Moodle 3.4.2. It appears that when we upload a file it takes like 10 seconds+ after the blue progress bar appears and completes before the file upload is complete.
But on theQA Moodle server it is close to instant. I am guessing this is a server issue rather than code issue.
Please see this video of the problem in action:
Any clues on what can be causing the slowdown?
