What impact does the compression in Session Replay have on the client browser?

The correct answer indicates that compression in Session Replay has minimal impact on the UI thread of the client browser. This is important because Session Replay functionality is designed to enhance user experience tracking without significantly degrading the performance of the user interface.

When Session Replay is utilized, compression algorithms help reduce the size of collected data, making it more efficient to transmit and store. This compression minimizes the amount of processing power and memory needed during playback, allowing the UI to operate smoothly. As a result, users can navigate the application without noticeable delays or interruptions.
