A bit new to performance testing and web architecture in general, but when looking at AJAX Requests that are being called, how do I know which ones being called at the same time versus ones that aren't? Some of them I can see on developer tools being called like :
"Queued 1.50s" for two AJAX requests. If it's like a .01s difference does that mean they aren't called at the same time? I'm trying to figure out which ones I will need to put underneath a parallel controller in JMeter to create the correct network path.
Requests have the same start time are "happening concurrently", like red rectangle in the below image of the browser developer tools
others are sequential.
"Queued" mean that browsers open up to 6 concurrent connections per domain for downloading embedded resources and/or executing AJAX requests so if your page has more than 6 AJAX requests defined only 6 of them will be executed at a time, others will be put into the queue.
