In the process of developing a JavaScript based application of significant size, I frequently encounter situations where up to eight (8) AJAX requests are initiated concurrently. In older browsers such as IE6, this can result in certain requests being terminated prematurely. Nonetheless, my focus is on modern browsers, hence IE6 compatibility is not a concern.
While I have not conducted any formal performance testing, I suspect that consolidating these requests into pools may enhance overall efficiency. For instance, limiting the concurrent requests to a maximum of 4 at a time.
Therefore, my inquiry pertains to the advantages of pooling AJAX requests versus allowing multiple requests to execute simultaneously without queuing them sequentially. Different browsers and Internet connections may yield varying results in this scenario, which I am uncertain about.
