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?
Just wanted to follow up with this that we found the issue to be the virus scanning. If we turn off virus scanning the upload is instance.
So we need to switch to daemon ClamAV: https://moodle.org/mod/forum/discuss.php?d=357724
