System Performance

Performance of the Eagle 250, like that of any computer, is application dependent. The best way to

determine actual throughput is to run an application and measure the results. If such a test isn’t

practical, benchmarks can provide a relative measurement.

The benchmarks in this bulletin are offered for general comparison analysis and example only. For

definitive measurements, VARs and end users should verify actual performance based upon their

specific applications and environments. The benchmarks we use give an overall indication of system

throughput. It’s important to note that the way your application software uses the system may produce

results different from those suggested by our benchmarks.

System Index (SI)

The SI benchmark measures processor and memory performance in the AMOS environment. The

measure is relative to the original WDC-based Alpha Micro computer, the AM-100, which was

arbitrarily assigned an SI of 1. See the table below; bigger numbers are better.

Keep in mind that the SI reflects processor speed only, not overall system performance as users will

experience it. Factors such as disk accessing and the effect of multiple users are not measured in this

rating.
