Help download M3U8 url video faster

[massafera]

Guys I read here on the forum that i have to use this code to download m3u8 files.

ffmpeg -i "M3U8 URL" -c copy -bsf:a aac_adtstoasc video.mp4

It works, but am i downloading the original video file? or am i downloading as if it were recording a stream? I know it is a stupid question but it is my first time trying this method.

And is there any way, any command i can use to speed up the process? it starts with a speed of 5.500X and it keeps getting lower until it reaches 0.0900x.
