Video blayback in mobile browser is very slow compared to Chrome or Firefox

The thumbnails of video loads quick but it takes a lot of time to start playback. Once started it goes OK but when skipped again buffering. I tried the same URL in Google Chrome and Mozilla Firefox and they both load the play the videos quick.


now when i checked the whole browsing experience is slower compared to chrome when the shield is on in case of mobile when tested with slow networks.
