      For version 8.0M2,
      @unknownuser said:

      (http://support.google.com/sketchup/bin/static.py?hl)":100134bg]SketchUp Writer C++ API: In earlier versions, ISketchUpGroup::CreateGroup became slower each time it was called. This shouldn't slow down any longer.

      I would think that this fix was added into the application code as well.

      @Guy: Is your friend's Mac running Sketchup version 8.0M2 ??

      We use on Mac and PC the latest version from google's website. (PC 8.0.11752/MAC 8.0.11.751)

      I did some more testing:

      model = Sketchup.active_model
      entities = model.entities
      puts '- Start test1 add_group bug on MAC -'
      start = Time.now
      for n in 1..1000 do #changed this setting for the testing
      	g = entities.add_group
      	g.name = n.to_s
      	point1 = Geom;;Point3d.new(n*10,0,0)
      	c = g.entities.add_cpoint point1
      end
      puts 'Total time; ' + (start - Time.now).to_s  
      

      Results: bugMAC.JPG

      At this moment we use a workaround. Place the groups in a new model (use the multiple documents on MAC), make a component of all the groups. Save this component and insert it in the model and explode it. The biggest problem of this workaround is that it's impossible to close the new temporary model with ruby. A other problem is that is still a lot slower than on PC.
      Anybody a solution?

        WoW! Excellent test report. Shows that the Mac still has a problem.

        I wonder if the difference has to do with Ruby.? The Mac is still running the initial release of v1.8.5, and the PC was updated to v1.8.6-p287.

        There is a thread on how to point the symbolic references for Sketchup Ruby to a "normal" full Ruby install elesewhere on the Mac's harddrive. (You need to backup the current links, so you can switch back if necessary. Perhaps a shell script?)

        I'd be interested in seeing the comparison for the Mac, running v1.8.5-p0 and v1.8.6-p287, ... (and perhaps even the latest patchlevel for v1.8.7)

        I'm not here much anymore.

          And here are the results for ruby 1.8.7 on mac:

          100 - 0.58 sec
          200 - 1.69 sec
          400 - 10.55 sec
          600 - 33.39 sec
          1000 - 147 sec

          Almost no difference with ruby 1.8.5 ๐Ÿ˜ž

            Bummer... definately the problem is in the C++ code.

              Looking at the add_group Ruby code, its the same on both platforms.
              One reason (don't know if this is true) it could be slower on the Mac
              is the notifications that are sent around could be updating the Mac
              UI, like the component browser. This may be more efficiently done on
              the PC.

              Also, the same code (duplicate code/cut-n-pasted it looks like) that
              I fixed in the C++ API was also being used in the Ruby code.
              The bug report only mentioned the C++ API, so that's what got fixed.

                I have noticed that if you use Sketchup.status_text within a loop it will be very slow under OSX. It seems that the UI is forcefully freshened all the time, while on Windows you get "white-out" and the UI stops updating - but completes the loop much much faster.

                But if it is the UI that slows things down, then running the test with start_operation and disable_ui argument set to true, should show a good performance increase, right?

                  @John: thanks for taking a look at this, and "weighing in."

                  @GWD: Are all these groups to be added REALLY have all the same objects (like the example,) and just have a different location (transform) ?

                    Dan,

                    No this is just a quick test that reproduce the problem. We have at this moment 2 totaly different script which have this problem.

                      I tested it with start_operation and it as no effect!

                        I just did some testing with adding components instead of groups (see script below). And the result is shokking. Placing 600 component give about the same time as the 600 groups 0.7 sec on PC and 27 sec on MAC. BUT after the script ended the MAC keep on showing the busy icon for very long time. More than 5 minutes (then i killed sketchup). I did the same test on mac with different number of components and this are the results:

                        50 components 0.29 sec running script 17 sec busy icon after script
                        100 components 0.85 sec running script 35 sec busy icon after script
                        200 components 3.8 sec running script 2 min 25 sec busy icon after script
                        300 components 7.6 sec running script more than 5 min sec busy icon after script
                        600 components 27 sec running script more than 5 min busy icon after script

                        require 'sketchup'
                        UI.menu("PlugIns").add_item("bugMAC Test2") {
                        model = Sketchup.active_model
                        entities = model.entities
                        puts '- Start test1 add_group bug on MAC -'
                        start = Time.now
                        for n in 1..600 do 
                        	newdef = model.definitions.add		
                        	newdef.name = n.to_s
                        	point1 = Geom;;Point3d.new(n*10,0,0)
                        	newdef.entities.add_cpoint point1 
                        	pt = Geom;;Point3d.new 0,0,0
                        	trans = Geom;;Transformation.new pt
                        	i = model.entities.add_instance(newdef, trans) 
                        	i.make_unique	
                        end
                        puts 'Total time; ' + (start - Time.now).to_s  
                        }

                            Not surprising that it takes the same time to add groups and components, because a group is a special type of component, that also has a ComponentDefinition (whose group? attribute is true.)

                            The extra time, likely comes from adding all that new stuff to the Component browser. (guessing, here.)

                            Close any unneeded toolwindows, especially the Object browser. And use an operation with the disable_ui flag set.

                            That's all we can say. I guess John indicated that there were UI issues with the Mac edition. (I'm not sure if he said the SDK updates did, or did not make it into the last build... he was a bit ambiguous. But internal politics, ya know....)

                            You can always file a bug report. The more people that scream...

                                ... your browser will open, to the Google Sketchup Contact page.

                                Use the "Bug Report" link, to bring up the form, and fill it out.

                                    Good news for Mac users. This issue has been reported as fixed in the 8.0M3 release.

                                    see: SketchUp Release Notes

                                    and get the latest MR at the SketchUp Downloads page.

                                      I would have loved it if they fixed add_face too. I've found workarounds, so i don't need it now, but still.

                                        The problem isn't fixed at all on mac. I did the test i posted before with the new version. On mac the script runs 250% slower on the new version. On pc the script runs 300% faster on the new version!
