Why do you think that 3x is few ? This is like a car running at 50 km/h versus one running at 150 km/h. I'd consider this much much faster.

Or do you refer to other tests not mentioned above ? Which OS do you run ? With OS 3.5 and 3.9 some ROM modules are replaced by the ROM update which means they are aleady in RAM and whether the ROM is copied to RAM or not does not matter. With OS 3.9 BB2 even the most important part of AmigaOS, exec.library, is replaced by a RAM module, so maprom does not mean much here, anyway.

Oh, yes !

Yes, of course !

>Which OS do you run ?

OS 3.9 with "SetPatch NoRomUpdate"

Someone can try with an Apollo (and RemApollo) to see if you get a speedup ?

Theorically, with the Kick in fast, the Workbench must run faster... I don't understand...

I don't think so. Icon.library is disk/ram based. Workbench.library is disk/ram based. With VisualPrefs and other common patches active most of intuition.library is disk/ram based. Graphics.library has not much CPU code but uses the blitter for most gfx operations. There is not much left which really runs from ROM.

Also if you have a fast processor with a big cache, many of the speed tests can be run from the cache without accessing the ROM chips.

The Kickstart is called all the time when we use the Workbench...

My 060 have only 8 ko of code cache...

And before in cache, the code must be loaded into !

Believe what you want. I told you that this is not the case.
