I got it working and kicked the tires a bit.
It would be useful to have such a tool in Pharo :-)
Now, time to dig.

Once the code is loaded, from the Tools menu use Hash Analysis Tool.
There's a manual below, and also the Fundamentals book has a somewhat in
depth discussion on how it works.

I have found the tools in the Cincom public repo.
Now, I have to see how this works in VW, I am not that proficient with it.

Hello again...
For what occurs in modern CPUs, well, no. Surprising to see that a mul
would be faster than a shr or shl. How comes?
No, not faster. But definitely way faster than >30 cycles not so long ago.
I used to be ok with these things when I was writing demoscene code a
loong time ago

Ok, but how much faster? 64x64 bit multiplication on modern x86 is just
8 cycles (!), and there will likely be parallelism done by the CPU
Andres,
Thanks for the insights.
hash quality is indeed an key factor. At least, my mind is somewhat
grasping this hashing field a bit better.
I'll have a look at the tools, I haven't used them yet.
And a shot at the ASM version with NativeBoost in Pharo.

I'd think so. I haven't been following discussions of 64-bit design for
Pharo. How many bits of identity hash
