3428.98s (extremely slooow ...almost 1 our) :shock:
But I did expected that: VM are not very performant
I cannot test it on real hw with Ubuntu OS ...

May be someone having both OSes on the same PC (dual boot) or having two PCs with similar hw could do a comparison between FC in Ubuntu and CAD-Assistant in Win

I have the necessary set-up but it will take some some time.

I am worried too. I create and set "HAVE_TBB" from cmake gui when configuring FreeCAD because it doesn't exist by default. I'll reproduce this on Ubuntu and compare the results.

@vejmarie, I had no problem building your OCCT7 fork with TBB.
I get these errors trying to build your FreeCAD/step fork

It could very well be how I'm linking your OCCT to FreeCAD.

would you mind to do also a comparison in loading time between FC latest dev release 9944-64b and CAD Assistant in windows on similar PC hw?
@vejmarie said that his TBB branch and the main branch should have very similar results in loading time, but on the contrary I have quite different performance (like 3:1 times)

Will do, but it seems vejmarie's occt patch is the key. Linking vejmarie's FreeCAD fork to official OCCT7w/TBB and to vejmarie's OCCT7w/TBB has been, in the past, around 2x (clock on the wall). Next week I should be able to test with easy-fc's script.
@vejmarie, on your local builds, for FreCAD how do you handle -DCMake HAVE_TBB=1? I could definitely be botching this.

I don't know where but i know i have seen it somewhere. That is @vejmarie figured out the progress indicator "refreshing" contributes to the performance penalty when loading STEP file. And he fixed that.

Thanks for doing that!

Hi, I am just turning TBB at cmake level with -DHAVE_TBB=1 ;).

Hi Triplus, you are welcome. The patch regarding the progress bar has been included last week, you probably have seen it going through the PR.
