    HITE APER (cont.) N T R O D U C T I O N T O I C R O S O F T I T E E R V E R As enterprise customers become more dependent on the Intranet, Internet, and World Wide Web, there is a tendency to get bogged down in the creation and management of web-based applications.

Internet Locator Server allows you to find others who are currently on line. It finds information that is constantly changing, such as a user’s IP address, and continually updates its information as users log on and off.

This operation must be done before any application can use ILS and is always done at least once by all ILS applications. The performance of the LDAP command sequence CONNECT, BINDSIMPLE ANONYMOUS, and QUIT was measured to simulate this operation.
  • Page 9 HITE APER (cont.) ILS Test Procedures The basic procedure used for performing the ILS tests was: 1. Automatically start IIS and the LDAP server at SUT boot time. This enables both IIS and LDAP logging. 2. Use the ASP-enabled Web page to create a simulated online user base of the appropriate size. 3.

    By doing a “what-if” analysis using this workbook, which Compaq computers, and how many are needed to support the specified number of users with a given response time, can be determined.
  • Page 21 HITE APER (cont.) Be sure that the network bandwidth is sufficient to handle the projected transaction rate. If the server will use a 100 Mbit/second network, bandwidth will not be a bottleneck. However, at least two 10 Mbit/second networks will be needed to handle the maximum transaction rate supported by either a ProLiant 2500 or ProLiant 7000.

  • Page 22: Conclusion

    System. ILS and PS performance measurements for both the ProLiant 2500 and 7000 have shown that they were capable of generating loads that fully utilize their CPUs. Microsoft Site Server, on Compaq ProLiant 2500 and 7000, delivers the return on investment businesses are looking for from their Intranet and Internet sites.
