I am currently developing a website where notification is needed. Therefore, I would like to call AJAX and detect changes on my database (storing notifications) constantly in a certain interval.
So my question is, as there are many users calling the AJAX at a same time and at constant rate, will performing such task burden the server?
And will this burden the browser for each users? I had a little bit of performance issues (slow loading / lag) when testing the website when I enable this method.
If this method is bad, can I have some suggestion for alternative method for this task?
Any help is appreciated =)
