The TCP routing node allows a multi-processor SP system to appear as a single web server, providing both scalability and ease of web site management. A total of 9 web client systems were used to measure the performance of 1 to 6 nodes as web servers. Each node was run with 256MB of memory per node, substantially more memory than was required for the Netscape Enterprise web server. Server Software Netscape Enterprise Server Version 2.0b4. Actual results may vary.
Values shown here are results of development level systems.
IBM recommends application-oriented testing for performance predictions and offers the above commonly reported benchmarks only as an initial indicator. The WebStone benchmark is a simple benchmark that has been used to characterize uniprocessor Web server performance. The benchmark uses a cluster of systems to query a Web server for a series of pages defined in a workload. The benchmark allows an adjustable number of simulated clients to connect to the server under test. Additionally, runs of other lengths of duration and multiple iterations were used to verify that results reported here reflect steady-state measurements.
