Ajax calls may take relatively longer time to complete than other ordinary web calls as there are many factors associated with its execution time which includes client-side factors, server-side factors as well as network factors. Any problem to do with networks, be it limited bandwidth, high latency, or dropped packets has a direct bearing on time taken to transfer information. Client side delay can be as follows: slow network connection, network or server load, delay in request’s backend processing, poorly designed SQL requests that require a lot of time, or APIs that take too long to meet the incoming requests. Furthermore, how much data one uploads or downloads, running JavaScript on the client side must be disabled or carrying out a lot of DOM manipulations after the response has been received.
If multiple AJAX calls are run in parallel or if they are, sequentially the browser or server may get flooded, which will take time to complete. This is because such as missing caching mechanism or having uncompressed data means that the response time can be affected. Moreover, one can assume that the usage of third-party API, or making cross-domain requests, can also add the delay. In the development or testing environment, the services could be designed with or without actual delays for debugging purposes, and the Ajax response time may also be faked.
These are some problems and to overcome it we have to focus our code in server side optimization, minimizing the size of response, implementing cache control and data compression. Another method is to use content delivery networks (CDNs), to optimize JavaScript executions, and reduce unnecessary changes within the Document Object Model (DOM). Overarching the identified ideas, it is necessary to pay attention to the monitoring of third-party APIs and the selection of more trustworthy services to optimize AJAX requests.
