    I am using AJAX & PHP at server for retriving data from the server after every 10 second cycle.

    Shoud I use setRequestHeader("Connection", "close"); after every call or remain connection open(Persistance connection) for the puspose of http requests & server load.

    Please suggest.

    A request every 10 seconds shouldn't load a web server too heavily, depending on how many users you expect to have at any one time. Note that a persistent connection requires HTTP/1.1 compatability on your web server.

    Consider the user first, then see if you have the server-side capabilities to provide that level of service. Try a benchmark between the two of them, and see how well your application responds.

    Thats my tuppence :)

    Its hard to tell really, I'm not sure what your script is trying to achieve and how much load is expected on each request.

    Personally I stay away from the theoretical maths, get my hands dirty and do an experiment to see which would be most efficient.
