A Principled Technologies test report 3
Web server performance: Dell servers
technologies work in end-to-end service-oriented, n-tier architecture. WSTest 1.5 is Microsoft’s modified
version of the original WSTest 1.0, which Sun Microsystems created. The WSTest 1.5 benchmark tests how
well an application server performs as a Web service host across varying Simple Object Access Protocol (SOAP)
object sizes. To this end, WSTest 1.5 measures the server’s ability to process HTTP/SOAP requests, integrate
Web servers, isolate the networking stack, and serialize XML engines. WSTest 1.5 consists of the five tests
(which WSTest 1.5 refers to as “web service methods”), which test the SOAP network stack/serialization
performance of the web server. Of the five, we are only using the GetOrder test, which simulates a complete
purchase order request.
The WSTest 1.5 metric shows the peak throughput, or number of web service requests per second a
server can handle.
SYSTEM COMPARISON
Figure 2 shows a side-by-side comparison of the key hardware differences between the servers.
Appendix A presents detailed system information.

WHAT WE FOUND
Figure 3 shows the WSTest 1.5 results, in requests per second, for the three Dell servers.
We ran WSTest 1.5 three times for each server, and report the results of the median run.
