Abstract : One of the goals of the Ada Embedded Systems Testbed (AEST) Project is to assess the readiness of the Ada programming language and Ada tools for developing embedded system. The benchmarking and instrumentation subgroup within AEST Project is running various suites of Ada benchmarks to obtain data on the real-time performance of Ada on a number of different target systems. The purpose of this report is to categorize the factors have been observed, while others are more speculative in nature. All these factors should be understood if accurate, comparable, and repeatable performance data are to be produced by Ada benchmarks. Keywords: Compilers; Timing anomalies; System software effects; Hardware effects.
