I'm not seeing any performance regression - looks rather consistent on this end.. I'm not sure why you are seeing a difference on your system.

Maybe you are right...
For people doing renderings 2015 is first professional version (thanks to 64bit and possibility to use whole memory).
From the other side v8 is last true free version (according to the license)...

Do you know any recent statistics on SU versions usage?

I have some data : http://thomashauchecorne.com/layers/analytics.php
But it's only about Layers Panel users (around 500 unique daily users)

Hi Thom, thanks for taking time to look at my code-problem.

I don't see big differences as well if I load components from the SketchUp Components sub-folder (see my post, two posts above your post).

Have you tried my original code (loading from root of C OR loading from the Sketchup plugins folder) and looked at the differences?

I tested your code and here are the results:

I still don't see any difference. Do you have a sample model to share?

Dan Rathbun

If a component has a classification assigned, the entire schema could be serialized into the skp file.

Upon loading the schema is loaded into the active model, correct TT ?

tt_su

Yup!

tt_su

Well, actually, I'm not sure what SU does when you import... Need to check that. But it could be that we load the schema.

I just did some tests with all kinds of code and you might be right it's my component files that are causing the problem. This one (see attachment) for instance takes 0.93 seconds to load in V15 while in V14 it takes 0.36

I'm puzzled...

edit:

the file in the attachment is 70kB in size. If I re-create it from scratch the file is 11Kb in size. Maybe there's something hidden/attributes that isn't purged using TIG's purge?

Ok - now I can reproduce this:

I'll forward this to the team. It looks to be related to the classifier system as after I removed the IFC schema and saved a new file:

The profiler will tell us exactly what it is. Thanks for the report.

I saved it as a componant and ...
