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 mean of the 10 experiments is given. Time is measured in seconds. This is true for values provided by TFM, but not for values from others (see history).
On CPC emulators the times can vary, for this tests only real CPCs has had been used. For this tests the Dobbertin HD20 hard disc had been used. The used PC had a AMD Duron CPU running at 900 MHz. It's OS was Windows2000. Instead of Vortex format 720K DOS format has been used.

To format a disc in DS/DD/80 track Vortex format VaraDOS needed to be used instead of ParaDOS.
=== Copy a disc: 40 / 80 tracks, one or two drives ===

In this examples XDX-DOS DDOS was speeded up using the !FAST RSX command. CP/M 2.2 did not sort the directory.

== Missing data ==
Some speed checks using [[ParaDOS]] remain to be performed (on a real CPC).
