WinUAE speed changes!

none of your machines have pannels on the cases

uh-oh....is this wrong?  :lol:

@ All
OK people!
The information is in for those of you that are interested.

I used the exact same SiSoft Sandra for both PCs.
My 1st post will be the Athlon benchmarks and the second will be the celeron if you want to save and compare the two.

My test results show the Athlon beats the Celeron is just about everything. So now, I must think that the JIT or something is coded for P4 type CPUs only.

@ Bloodline

I'm sure I already have said that I am using exactly the same WinUAE settings from work at home.
I copied the entire WinUAE directory from the work PC and installed it as is on my home PC just to be sure!

It most certainly can not be WinUAE settings however you may be right with using that term settings as it could be my Windows settings. I have no idea if Windows XP is superior to Windows 2000 so you may be on to something.

The funny thing is, it's just such a HUGE difference in performance. It's almost like I have 4 CPUs working together in the work PC when I compare it to the home PC.

I wouldn't think that windows XP could make that kind of an improvement.

Well that settles it then, there seems to be only one thing left to do now.
Install Windows XP on the home PC and test it all over again.
I have to get a copy of the XP OS first, I never liked XP so I only ever bought 2000. I don't like being told what I can or can't upgrade on my computer and Windows XP has that protection to stop you upgrading key components like CPU etc.  Wrong wrong wrong...Must kill M$

@ all
What do you all think??

[Damion]

Looks spot on to me. You should be decimating the Celeron, especially in the "math" test which is what is
going to matter for WinUAE. I would suspect something in the program configuration (are you sure JIT is enabled??)...might also try again after installing XP. Overclocking would definately give you a nice
performance boost (especially upping the FSB a little) but it seems you have a software problem somewhere.

[SHADES]

@ D

Hi, ALL WinUAE settings are identicle for both PCs.
It is a direct copy of the work PCs WinUAE directory just to remove any doubt on my end.

I can't overclock the FSB too much, my tollerence for other components don't like to go too far and light overclocking on memory etc didn't show much improvement on AIBB benchmarks.
I agree in the software problem, just trying to find where that could be in Windows is beyond my knowledge. Windows is a pig.

[Damion]

Where can I download the AIBB benchmarks you ran? I'd be willing to clock my Athlon identical to yours, then run the benchies as per your instruction...that should give us a rough idea of where you should be after installing XP.

[Trev]

He he. Sometimes, it just won't stop flapping. :-P So much to learn! But it never hurts to try and reason things out on your own. I do, however, make a mean bowl of oatmeal, so at least I have that. :-)

By a 1:1 memory mapping, do you mean as done by the operating system's virtual memory manager? Or the JIT engine itself?

Slightly off topic, but how difficult would it be to modify the JIT to support (i.e. work around) the new no execute flag? A simple change in the OS-specific memory allocation flags?

Trev

[SHADES]

@ D

Hmm.
I'll make some tonight, LHA em up and mail them to you if you like?

It will have to be when I get home as I'm at work now.

[Damion]

Sorry m8ey, I meant where can I download the AIBB program, I'd never tried it until now. :-)

I found it, downloaded and played around with it a bit, and although the results were significantly faster
than the machines included with the program (obviously), they were also very erratic, differing wildly with each run. Some of the tests using RTG modes were also way off.

I've had better luck in the past with SysSpeed, AmigaMark and maybe P96Speed (for graphics).  
 
Here's to Thursday...only one more day to go this week
:pint:

[SHADES]

@ D

True, they would differ under emulation. Most things will as the JIT would cause havoc.

Even so, it dosen't explain why the work PC feels so much faster graphicaly than the PC at home, it's what made me try a few benchmarks in the first place, just to make sure I wasn't just feeling things.

In AIBB I run the default PAL 8 colour tests. No UAE native modes, just classic AMIGA modes for the testing. I do the same  for both PCs.
Really, it's not going to be accurate however, it also should't deviate to the point of being unrealistic from similar speed PCs.
It gave me the opinion that something funny was indeed going on and that the PC at home (win2k PC) was most certainly seeming slower than the XP PC at work. That has lead me to this point. Testing with the help of others.

I'm not sure what's going on here, but the Celeron XP PC certainly  seems to be faster than my Athlon, and the strange thing is, the Athlon is the faster PC.

[spirantho]

It sounds like your JIT just isn't working...

I just tried AIBB on my WinUAE install (Athlon 1600+) - your machine should smoke this one.

Did an AIBB emutest with JIT enabled and it was waaaay faster than a real Amiga 4000 (scored about 250). Did the same without JIT and it was about 75% the speed of an A4000/040. Not surprising really, given that JIT is exactly what's needed for tight loops etc. (so don't go thinking that WinUAE with JIT or not is ever really 30 times the speed of an A4000 - it's not, unless your only use for WinUAE is to run benchmarks, anyway. )

Oh, I'm running Win2K Pro, 768MB RAM, latest version of WinUAE. Sounds like you have a software configuration problem somewhere....

[SHADES]

@ ALL

Ok, this is really strange, but because i don't have a windows XP install disc, I resorted to re-installing windows 2000 from scratch.

After that and installing all the relevent patches, i re-installed WinUAE from the archive I had from the work PC and it is now functioning faster.

I'm not sure what was wrong in my windows setup, but there you have it, problem solved.

It just goes to show you how BAD windows really is and it's just another reason I now have to hope Hyperion hurry up a little and bring out OS4 because I no longer want to run this garbage.

Thanks to you all for your help here, it certainly was interesting to find out this fault.

[Trev]

Not sure I see the logic in that. . . .
