demo
In Safari 11 on both macOS and iOS, it often takes a long time until an audio (e.g. MP3) starts playing after starting it (especially on slower mobile connections).
Safari 11 buffers very much until it starts playing. In the demo I've attached, after you click the button, Safari buffers around 100 seconds of the audio before it starts playing, which seems way too much for me (also notice that the "playing" event is triggered and the loudspeaker icon shown in the URL bar and tab before it is really playing, i.e. it is audible and currentTime is increasing). (The effect is more obvious if you use Network Link Conditioner and throttle your connection to average 3G.)
In other browsers, the audio also starts way earlier, see this video comparing with Chrome and Firefox: http://www.yourfilelink.com/get.php?fid=1464049
This regression seems to have been introduced with Safari 10 on macOS and iOS 10; on iOS 9, audios start playing almost immediately. Here is an image comparing iOS 9 and iOS 10: http://i66.tinypic.com/25ppeoi.png
Thank you!
