碩士 === 國立臺北科技大學 === 資訊工程系 === 106 === When a Client-server service deployed, we need to know the number of users that can be handled by the system without significant delay. We do this by testing system’s behavior under intense loads, if the system delay, analyze the cause of the delay and improve it. In this thesis, we will use JMeter to write the stress test script, and execute stress test to understand how many users can connect to the system at the same time without delay. We compare three methods of WebSocket, WebRTC, and Socket.IO, and evaluates the feasibility of these three methods. According to the result of the experiment, WebSocket cannot effectively improve the delay, and WebRTC cannot gives the user good user experience. Socket.IO can improve delay effectively and gives the user a better experience.
