通过websocket在Web浏览器和python之间进行大量交换来阻止浏览器

I use websocket for exchange between Robot on Raspberry Pi under python, and web browser application with html, js and jquery. Robot gives its angular position coming from magnetometer chip, and webbrowser display robot direction. WebBrowser receives at least 5 messages by second, and block. How to gives some "breathes" to the browser to avoid that ? Best regardsI use websocket for exchange between Robot on R
