Speedcheck

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.

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.

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.

Disc management

Various measurements of the floppy disc speed (3" internal or 3.5" external) or hard disc speed (Dobbertin HD20) have been taken.

Format a disc: 40 tracks (Data) or 80 tracks (Vortex or 720K Dos)

Format	FutureOS	XD-DOS	Disc'o'Magic	CP/M 2.2	CP/M 3.1	Utopia	Windows 2000
Data	16	17	18	33	33	43	n.f.
Vortex	64	65	n.f.	65	n.f.	n.f.	104

Copy a disc: 40 / 80 tracks, one or two drives

Tracks & Drives	FutureOS	XD-DOS	Disc'o'Magic	CP/M 2.2	CP/M 3.1	Utopia	Windows 2000
40 tracks, 1 drive	20	n.f.	42	66	63	71	n.f.
40 tracks, 2 drives	20	n.f.	42	69	69	69	n.f.
80 tracks, 1 drive	77	n.f.	n.f.	257	n.f.	n.f.	n.f.
80 tracks, 2 drives	76	n.f.	n.f.	207	n.f.	n.f.	n.f.

Copy a file of 40 KB, 176 KB or 400 KB with two drives or partitions (HD20 hard disc)

Read a file of 40 KB, 176 KB or 400 KB from floppy-disc or hard-disc (HD20)

Write a file of 40 KB, 176 KB or 400 KB to floppy-disc or hard-disc (HD20)

Size & Device	FutureOS	XD-DOS	Disc'o'Magic	AMSDOS
40 KB, floppy	2,5	12	5	12
40 KB, hard-disc	1	4	n.f.	n.f.

Read a full directory, sort it and display it on screen

Format	FutureOS	XD-DOS	Disc'o'Magic	CP/M 2.2	CP/M 3.1	AMSDOS	Windows 2000
Data	1	3	2,5	3,5	12	5	1,2
Vortex	1,5	6	n.f.	6,3	23	n.f.	n.f.
HD20	12	20	n.f.	18,9	85	n.f.	1

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

Erase 64 (Data format), 128 (Vortex format) or 512 files (HD20 hard-disc) at once

Entries	FutureOS	XD-DOS	Disc'o'Magic	CP/M 2.2	CP/M 3.1	AMSDOS	Windows 2000
64 entries	1,0	27	1,5	26	15	27	33
128 entries	1,0	52	n.f.	51	29	n.f.	n.f.
512 entries	2,0	43	n.f.	25	11	n.f.	6

FutureOS clearly beats Windows 2000.

Missing data

Speed checks using ParaDOS and SymbOS remain to be performed (on a real CPC).
