Microsoft ISA Server 2000 Takes Top Honors in Cache-Off

REDMOND, Wash., Oct. 24, 2000 — In the industry’s leading independent caching competition, Microsoft â Internet Security and Acceleration Server 2000 (ISA Server), a member of the Microsoft .NET enterprise server family, demonstrated its superior Web-caching performance. The Measurement Factory Inc., of Boulder, Colo., applied the Web Polygraph test to 31 caches from 15 different organizations; ISA Server was rated No. 1 in price/performance and received high honors in throughput (requests per second) and in hit ratio.

“We’re thrilled with these results. The Cache-Off proves that ISA Server delivers exceptional performance at the best value in the market,”
said Paul Flessner, senior vice president of .NET Enterprise Servers at Microsoft.
“Customers want fast and secure Web access that’s easy to manage. With the best price/performance ratio in the industry and exceptional throughput, ISA Server’s integrated Web cache and firewall can satisfy the most demanding Internet environments and lower network costs, while also delivering enterprise security and policy-based management.”

ISA Server is a member of the Microsoft .NET Enterprise Server family of server applications for quickly building, deploying and managing integrated, Web-based solutions.

No. 1 in Price/Performance

Caching solutions differ in throughput, hit ratio and price; the price/performance ratio provides customers with a standard metric that can be used to compare products on a normalized basis. ISA Server posted the top score with 78 hits/second per $1,000 and 145 requests/second per $1,000, outperforming every other entry by 16 to 600 percent, clearly establishing ISA Server as the best value for delivering fast Internet access. The price was based on ISA Standard Edition, priced at $1,499 per processor.

Top Five in Overall Performance

Demanding Internet environments require high-performance cache servers. ISA Server’s 2,083 requests/second secured its position in the top five overall performance leaders, more than twice as high as the average product throughput of 887 requests/second.

Significant Bandwidth Savings

Higher hit ratios translate to bandwidth cost savings and improved Web response by delivering more content from the cache rather than from the origin server. ISA Server achieved a fourth-place finish with a document hit ratio of 55.2 percent out of a possible 58 percent, demonstrating its ability to deliver exceptional bandwidth savings.

The ISA Server cache accelerates users’ access to the Web and saves bandwidth by storing popular Web content on the corporate network, eliminating the need for repeated retrieval of the same content. Web server administrators can use it to accelerate access to a Web server or e-commerce application, to offload processing from the Web servers, or to more efficiently distribute their content to end users. ISA Server includes high-performance RAM caching, hierarchical caching and scheduled content download.

ISA Server Redefines Caching With Integrated Security and Policy-Based Management

While the Cache-Off results establish ISA Server as a leader in caching performance, customers want more than a fast Web cache; they require Internet connectivity that is secure and manageable as well. ISA Server eliminates the traditional tradeoff between network security and performance by integrating an enterprise firewall with the Web cache. Whether installed separately as a firewall and Web cache, or integrated on a single machine, ISA Server provides a unified policy, access control and management interface.

“With ISA Server, customers have a solution that provides exceptional Web access performance and strong Internet security,”
said Flessner.
“This product embodies our commitment to secure computing that gives our customers the performance they need to compete in the digital age.”

The RC1 prerelease version of ISA Server and more information on the product are available at . The product will be released by the end of 2000. The official Cache-Off results and independent analysis are available at
