Performance

Compaq has an ongoing program of performance engineering,

using industry-standard benchmarks that allow comparisons

across major vendors’ systems. These benchmarks against

competitive systems are based on comparable CPU

performance, coupled with comparable memory and disk

expandability.

See Table 1 for the record-breaking performance numbers of

the AlphaServer ES40 systems. For example:

•

SPECweb96 Internet Server — 11,159 operations per

second, using an AlphaServer ES40 UNIX system with

four processors

The SPECweb96 benchmark focuses on server performance

for static Web pages, measuring the ability of the server to

service HTTP requests or “gets.” One or more clients are used

by SPECweb96 to send the HTTP requests to the Web server.

The software then measures the response time for each

request. At the end of the benchmark run, SPECweb96

calculates a metric based on overall throughput, measured as

maximum benchmark operations per second.

System performance, however, is highly dependent upon

application characteristics. Thus, benchmark information is

one helpful “data point” to be used in conjunction with other

purchase criteria such as features, service, and price.
