To me, a 10x improvement over a 50mhz 68030 sounds like a very impressive mark!
Especially for a processor as crappy as a Celeron!
I mean, that's an emulated 500mhz 68030.
From a budget low-cache 2600mhz chip.
*/
But Sysinfo says the emulated machine is 108 x as fast,
Sysinfo is not measuring the Celery chip but the emulated 68k chip,
can you put my CPU in perspective in terms of cache size + speed
relative to other Intel clones?
The startup seems to say 128K cache, I know that cache size makes a huge
difference to performance,
/*
That's only 5 Celeron cycles per emulated 68030 cycle.
Honestly, I doubt the emulation (even with JIT) is that tight.
*/
ok, I see what you are saying, 2.6GHz sounds much more impressive than
50MHz, but actually its just a ratio of 50,
so your numbers are exactly right,
what does the 400MHz mean in 2.6GHz/400MHz?
400 million cycles per second, but how many bits happens per cycle and where?
/*
As you found, file I/O plays a huge factor in compile times.
I imagine your Amiga HD is probably slower than the hard drive on your emulator.
This is slowing down the Amiga's compile time...
*/
Sysinfo crashes if I try to measure the disk speed on the PC,
if I access the file system on WinUAE it takes forever, eg typing tab for tab
completion can literally take minutes before the requester appears: even if there are
just 3 items in the requester,
on my A1200 tab completion only takes ages if there are a lot of items in
the requester,
cd and assign also can take forever,
I will try and do some experiments to determine whether the slow file access
is from WinUAE or if its an XP problem,
I have 4 shells currently: AmigaOS + Geek on WinUAE
and Cygwin + MSDOS on XP, so I will gradually
compare these different shells to try and pinpoint the
slowness,
Windows XP seems very secure in some sense of the word, so I wonder if
XP is doing some very inefficient vetting of each file access?
OTOH XP is very insecure in the sense that it is continuously under siege
from viruses, this system expects me to do a full Norton scan once a week,
I dont trust Norton, I think Norton is spying on everybody's system and submitting
reports to some CIA database. Is Norton looking for
viruses, or is it a spy?
Once a file is accessed then it can be processed unbelievably fast,
/*
And, of course, the real moral is, don't believe artificial benchmarks
run on emulated systems.
*/
IMO a lot of damage has been done to the Amiga market by lies about Windows
machines,
I have my setup now so that by turning a KVM switch I can alternate between
my AGA A1200 and this XP PC,
I am very happy with WinUAE except for the file access slowness,
the AGA emulation is very impressive eg it does perfect emulation of
AGA HAM8, it also correctly does slide down screens,
USB2 is said to manage 480 Mb/second, and the machine has a zillion
USB2 slots, however I cannot run my external USB2 hard disk and
the Disgo flash ram at the same time!
:so this USB2 cannot cope with just 2 USB2 devices, I phoned the manufacturer
of my PC and they say it may be a power problem, the Disgo drive takes
its power from the PC,
The PC also cannot cope with keyboard + mouse extensions beyond 1.8m,
my A1200 is quite happy with eg 5m extensions,
so I am finding my A1200 better engineered,

Aren't there 1000 threads about this on here?

probably, but I wanted to dispell some of the pro Windows FUD,
propaganda is based on the idea that if you keep repeating a
false statement often enough people will start believing it
at a subconscious level regardless of its falsity,
its Pavlovs experiment of the dog + food + bell,
eventually just ringing the bell made the dog salivate,
I have a book which says that Pavlovs experiment formed the basis of
the S.U's propaganda machine,
the never ending Windows FUD made me believe I was buying a
miracle machine, the only way to break the FUD is to repeatedly switch
between the 2 systems and do experiments,
There has also been anti Windows FUD, eg this PC is
very quiet and its not hot. So all that stuff about
PPC being cool and quiet, well so is my PC,
I think a big advantage of PPC is that it is a
very clean architecture, so it will probably
be much more immune to viruses and MS (IYSWIM),
