Sorry, I can't resist. I read this in comp.sys.atari.st:
copy 40 files (smallest = 1KB, largest = 200KB, total size = 530KB)
from partition D: to a new directory on partition C: (partition
C: is 10MB, with about 5.4MB free).
command given at msh prompt: time "cp * c:\tmp"
without FATSPEED time returned: 0:07:27.500
with FATSPEED time returned: 0:02:58.275
That's over 2.5 times faster!!
I had to perform the test on my Amiga. As close as I could, I created
40 files from 1K to 200K in one partition, totalling 538KB, and then
copied them all to another partition. The time it took:
17 seconds
That's over 10 times faster the fast time above; 25 times faster than
the slow time! (Of course, I'm sure this isn't a fair test somehow.)
But I remember all that stuff I read about Atari having such a fast
hard disk interface and all that.
Oh, my hardware? 2090, with CDC Wren SCSI drive.
And to copy a single 530K file from one place to another takes only:
3.5 seconds
as near as I can tell. (Just reading or just writing is, of course,
much faster, because the seek time disappears.)
Enough of this.
