| Summary: | 17 seconds per connection using a fraction of the expected browser's results, having a response time of between 12 and capabilities, a WWW-based in-class-response system is communication, shorten response time to questions and developed from which the instructor can obtain instant distributed scenario for an in-class response setting (e.g., enhance overall teaching performance. One of the concerns expected 100 requests in a 30 second window. These results FastCGI shows the performance improvement which stems from feedback about the student's comprehension level during for an in-class setting. A much lower response time and a having 100 students accessing the server in a 30 seconds having a configurable number of processes running on the Web higher throughput was obtained after installing the CGI Implementation of the FastCGI interface on the Web Server is increase overall learning. Immediate access to the students' initial stages of this research, led to the implementation to instructor a chance to initiate early corrective action and instructor-student interaction, students can improve leads us to conclude that the Web Server based on the Ultra lecture. Using a Web browser in class as a form of load, leads to the conclusion that the original testbed based on a SPARC I will not be able to sustain the expected load performance problems caused by the large number of programs on a Ultra Sparc 2. The benchmark tests using 84 response to questions posted in-class will give the resulting from the use of such a system in an in-class second using the CGI and FastCGI access method, respectively. server overload. Server to serve the concurrent requests. A uniformly setting, however, arises due to the potential problem of Sparc 2 will be able to handle the expected in-class load, at submissions within such a short time. Observing the than one second per connection using a higher load than the the much higher expense of the latter machine. the proposed solution to overcome this problem. the same one to two minute window, there may be Web server The Web browser tests showed an average response time of less unsatisfactory performance of the Web Server during the used to minimize response time. A comparison between CGI and Using the current network infrastructure and the Internet Webclients showed a throughput of 17 and 194 connections per window), would require a service rate from the server of With a classroom size of 50 to 100 students working within |
