The speedups of the Perfect Benchmarks codes that result from automatic parallelization are reported. The performance gains caused by individual restructuring techniques have also been measured. Specific reasons for the successes and failures of the transformations are discussed, and potential improvements that result in measurably better program performance are analyzed. The most important findings are that available restructurers often cause insignificant performance gains in real programs and that only few restructuring techniques contribute to this gain. However, it can be shown that there is potential for advancing compiler technology so that many of the most important loops in these programs can be parallelized
