multiple jQuery post very slow

Since we have our new server we have some issues with calling multiple jquery posts.

On some pages we call multiple jquery posts like this:

$.ajax({
    type: "POST",
    url: "../files/processed/includes/process.php",
    data: $('#myform').serialize(),
    complete: function(data)
    {
        $('#results').html(data.responseText);
    }
});

$.ajax({
    type: "POST",
    url: "../files/processed/includes/folders.php",
    data: '',
    complete: function(data)
    {
        $('#getFolders').html(data.responseText);
    }
});

The last post always wait for the first one. On our old server this was no problem and both posts loaded at te same time.

With a small change I speeded up a little but not as fast when used our old server. Strange thing is that the resources on our new server are much better.

The change I mentioned is:

$.ajax({
        type: "POST",
        url: "../files/processed/includes/process.php",
        data: $('#myform').serialize(),
        complete: function(data)
        {
            $('#results').html(data.responseText);

            $.ajax({
                type: "POST",
                url: "../files/processed/includes/folders.php",
                data: '',
                complete: function(data)
                {
                    $('#getFolders').html(data.responseText);
                }
            });
        }
    });

Is there another fix to load both posts at the same time or at least to speed it up?

On the server perform session_write_close() as soon as you don't need to modify session data.

Otherwise the second request waits until the first one holds the session file locked. And the lock is released after the first request ends.
