I am developing a live chat software in LAMP. For updating or handling the chat requests it uses it uses around 9 concurrent ajax server requests. In this case 360 requests per user per minute(approximately). Which is overloading the the server.
If i am making all these as single ajax requests, it will increase the processing time and which will reduce the product performance. As i am using mysql for storing is there will be an delay after long run of the software as history is saved in the database.
Thank you for your suggestions.
