Bear in mind that 95 seconds of "wait" time is hard-coded in our chat script, so total script response time will never be faster than 95 seconds. Also note that in addition to this wait time, total script response time includes time to log on, select a course, open the chat room, send 4 messages, and log out. Here is the response time graph for the current production build, here is the graph for the updated build. In both graphs, the upper-most plot indicates the script emulating 50 users in a single chat room. Notice the gradual degradation in response times for both builds. Essentially, the room is slower to load and refreshes take more time as the number of chat messages increase. However, the degradation is much more severe in the current production build.
