[Gmsh] Slow opening with multiple opencascade geometries

[GIORGIO PALMA]

Dear all,
I'm using the 3.0.6 version of Gmsh.

I'm generating my geometry (attached) using multiple boolean operations with the OpenCascade kernel.
When I try to increase the complexity of the geometry, adding more obejcts, things start to go bad:

time required for opening the geo file increases exponentially, I'd say not acceptably.

Can you suggest any workaround?
Thank you,

Giorgio Palma
