Performance SDK
The size of the SDK that will run on the client's page is directly linked to which features of it will be used. The more distinct functions called by the user's page, the greater the network traffic required to retrieve such features from the CDN. All of this happens asynchronously and on demand, which means that to use our services it is only necessary to download a tiny file of just 6KB and, as needed, the SDK itself takes care of downloading the necessary features asynchronously without affecting the initial page load.
📢 By utilizing lazy loading technique, when a new SDK feature is requested, the system will need to download the corresponding package only once. After that, this function can be called as many times as necessary without additional downloads.
🌐 Additionally, the bundles files, which are downloaded on demand, are also saved in network cache and local cache (on the user's computer). Therefore, after the first page load, where a few KB of the library are downloaded, future loads will already be pre-saved in disk cache on the user's computer.
