Performance investigation

[jr-accurate]

Hi,

I'm trying to generate the geometries for a larger IFC project using the IfcOpenShell-plugin, which takes quite a bit longer than I would've expected (or hoped for, anyways ;) ). Sadly I can't share the model, so I'll definitely have to do the investigation myself...

Here are my questions:

• Is there a way how I could figure out what's taking so long, like fine-granular logging or something similar?
• Are there any settings that could impact performance, and how would I get them to IfcOpenShell?
• I only need the geometry of a subset of objects. Is there a way I could let the RenderEngine know which ones I need and which it can ignore?

I'm happy for any other suggestions (including if there's a better place to ask questions like this)!

Have a look at https://github.com/opensourceBIM/IfcOpenShell-BIMserver-plugin/blob/master/src/org/ifcopenshell/ClientRunner.java you can run the generation process from the command line. If you add some time stamps to the java code yourself you have your fine grained logging to isolate the product(s) that takes a long time in IfcOpenShell.
