Nginx optimal speed in limit_rate for video streams

[c0nw0nk]

So when dealing with mp4 etc video streams what is the best speed to send /
transfer files to people that does not cause delays in latency / lagging on
the video due etc.

My current :

location /video/ {
    mp4;
    limit_rate_after 1m;
    limit_rate 1m;
}


On other sites when i download / watch videos it seems they transfer files
at speeds of 200k/s

Should I lower my rates ?
