Hello everyone,
anyone of you know why, with a simple 68 Mb file (see below)
I have a commitment of more than 3 GB of memory ... (see below)
Any suggestions to reduce the amount of memory? thanks so much

Because with autoCAD, 64 MB is not a simple model. On top of that because ASD uses custom objects, it stores more data in the file than vanilla AutoCAD would, so you can have more objects in a smaller file than if you were using plain AutoCAD objects. To test this use the export to AutoCAD option.
The video card has to work just as hard to display the shapes regardless of whether you're using AutoCAD solids or custom objects.
Also, you're probably showing a bunch of nuts and bolts which are extremely memory intensive. You'll probably see better performance if you freeze some of the object layers.
Autocad becomes lazy when Drawings are generated. I see 2 possible solutions for a "smoother" experience
1) Split the project in multiple projects (there is this option)
2) From model create separate files with each drawing. (the downside is that if you make a modification, it will not be reflected in previously created files.
A lot of people use Xref's to manage large files, it works pretty well. You may have to break up structural model along member type + level.
See, that's the thing. The program isn't designed for big steel structures. Any program built on top of AutoCAD currently is not designed for BIG. You can always spend more money, there just comes a point where the money spent is less than the gain received. Only you can justify how much to spend.
Your RAM and video card are a bit weak. I got with a Nvidia Quadro 2000 at least (1 GB of RAM on the card), bump up your RAM on your computer to 16 GB and you should see a decent performance boost between the two. I wouldn't spend much more than that.
Here's some reviews by Cadalyst:

If you're trying to visualize everything at one time, Revit has better performance than AutoCAD. ASD works, but you have to be willing to using xref's...like most people do with 3D inside of AutoCAD. Even Revit will have its limits.
ditto about the Graphics card and ram
the quadro5000 goes very well but the 2000 should do the job, id love a 6000...maybe if I win the lotto.
we split xrefs into :
floors
columns
vert bracing
hor bracing
stairs
etc
If you use XREF how do you connect the columns with the bracings for example ?
sounds that you should work rendering the biggest galaxy!!! is a disgrace you need to invert/put/waste too much money just using ASD, other programs run full mode using 2gb RAM.
Lanzman you have best computer, no need to change it, man i have just a regular laptop with core 2 duo, 8gb RAM and Nvidia geforce gts 9800m, and 6 months ago i just switch from ASD to Graitec Advance steel who also works on Autocad platform and from my experience Graitec can magae Autocad better then Autodesk itself, When i was working with ASD even for small projects my Ram was always on 100% but now max used RAM with Graitec is just 3 Gb for bigger projects. My opinion is stop investing in your beast machine just invest in new software 😄
I agree with ZHUKOV_ING about the absurldy high system requirements of ASD compared to Advance Steel . Bottom line is that the 3D model appearance is quite the same (except that in Advance Steel the welds are just a cross symbol) but AS is much lighter that ASD , so it's not an impossible task to make the program much lighter , it's its biggest flaw.
PS AS is a great program but it has quite a few things that in my opinion are much better in ASD . If I could combine the two programs into one it would be almost perfect .
My opinion: any other program works very well for large projects: AS, PS, Tekla and (rest in peace) Strucad.
