TEST REPORT

JULY 2006

KEY FINDINGS

z The Intel Server Board S5000PAL with

Dual-Core Intel Xeon processor 5160

delivered a 41.1 percent higher peak

WebBench performance than the Intel

Server Board SE7520AF2/Dual-Core Intel

Xeon processor 2.80GHz-based server (see

Figure 1).

Executive summary

Intel Corporation (Intel) commissioned Principled

Technologies (PT) to measure the WebBench

performance on two Dual-Core processor-based servers

using the following two motherboards and processors:

z Intel Server Board SE7520AF2 with Dual-Core

Intel Xeon processor 2.80GHz

z Intel Server Board S5000PAL with Dual-Core Intel

Xeon processor 5160

WebBench 5.0 (128-bit US version) is an industry-standard benchmark for Web server software and hardware. It

uses PC clients to send Web requests to the server under test. It generates performance results by incrementally

increasing the number of clients making HTTP 1.0 GET requests to the Web server; the result is a curve showing

the performance of the server under test. The peak of that curve represents the peak throughput of the server.

WebBench reports results in both the total number of requests per second the server handled and its total

throughput in bytes per second. To be certain that we found the true peak performance in our testing, we

measured the processor utilization on the servers and made sure that it reached or was extremely close to 100

percent during the test.

Figure 1 shows the

median WebBench peak

results, in requests per

second (rps), of the two

test servers.

To obtain the

median results, we

performed three runs with

each server and selected

the middle peak result of

each.

A higher number of

requests per second is

better, because the more

Web requests a server can

handle, the better.

Figure 1: Peak (dual processor) performance of the test servers running WebBench 5.0. Higher

numbers of requests per second are better.

As Figure 1 illustrates the

Intel Server Board

S5000PAL with Dual-Core

Intel Xeon processor 5160

produced the highest

result of 40,679.7 rps. This

result is a more than a

41.1 percent performance

increase over the Intel

Server Board

SE7520AF2with Dual-

Core Intel Xeon processor

2.80GHz, which achieved

a score of 28,837.8 rps.

Test results We ran WebBench’s default ecommerce API test suite, which generates both secure and non-secure static and dynamic HTTP 1.0 GET requests. While running the ecommerce suite, the clients must negotiate to a secure Web server port using the Secure Socket Layer (SSL) protocol. WebBench incrementally increases the number of clients making the HTTP 1.0 GET requests to the Web server.

Figure 3 shows a graph of the WebBench requests per second results for the test server. This graph illustrates the server’s performance under load for each of the 16 client mixes. As the number of clients increases, so does the load on the server and the number of requests per second the server must perform. During the first couple of mixes, the client count is low, so the server can handle the load with capacity to spare.

Figure 4 shows the WebBench throughput results, in bytes per second, for both servers. As with the previous graph, a higher peak is better.

Another hardware difference between the servers was the number of processor threads, though both systems offer four processing cores. The Intel Server Board SE7520AF2 with Dual-Core Intel Xeon Processor 2.80 GHz contained Dual-Core processors with HT Technology for a total of eight threads. The Intel Server Board S5000PAL with Dual-Core Intel Xeon processor 5160 contained dual-core processors. With the following exception, we used the default BIOS settings on the server: we disabled the HW Prefetcher.

Installing Internet Information Services WebBench requires a Web server, so we installed the Windows Internet Information Services with the following procedure: 1. 2. 3. 4. 5. 6. 7. 8. Click Start -> Control Panel -> Add/Remove Programs. Select Add/Remove Windows Components. Highlight Application Server and click the Details button. Check the Internet Information Services (IIS) item, and Click OK. Make sure you select enable ASP during the IIS installation. Click the Next button.

20. In the right panel, highlight All Unknown ISAPI Extensions and click the Allow button. Acknowledge the IIS Manager warning that appears by clicking the Yes button. 21. In the right panel, highlight All Unknown CGI Extensions and click the Allow button. Acknowledge the IIS Manager warning that appears by clicking the Yes button. 22. Close the Computer Management window.

6. Click [Submit]. Acknowledge the “Potential Scripting Violation” by clicking the [Yes] button. 7. There should now be a page informing that there is a Certificate Pending. Issuing the server certificate Next we had to issue a server certificate as follows: 1. 2. 3. 4. 5. Select Start -> Programs -> Administrative Tools -> Certification Authority. Click the server’s name. Select Pending Requests. Right click Pending Requests, select All Tasks, and choose Issue. Close Certification Authority.

We then set the following operating system tuning parameters to reflect the WebBench recommendations in the Microsoft Performance Tuning Guidelines for Windows Server 2003 document, available on Microsoft’s Web site.
