This article provides information about the real measured speeds of the CPC's hardware using different software. The abbreviaton "n.f." means "not feasible", since some software is not capable of performing a particular task. Numbers in bold indicate the smallest needed time. All experiments have been repeated 10 times, the statistic means is given.
On CPC emulators the times can vary, for this tests only real CPCs has been used. For this tests the Dobbertin HD20 hard disc has been used.
