      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) ?

          I'm not here much anymore.

            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...

                        Open Sketchup... pulldown the Help menu, choose "Contact Us" ...

                        ... 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!

                                      Hi,
                                      after a lot of digging, it appears that your test code will run in 0.8[1..3] seconds on both Snow Leopard and Mountain Lion with free or pro SU v6, v7 or v8, UNLESS you have either of these in your preference list
                                      %(#FF00BF)[<string>OutlinerController</string>
                                      <string>ComponentGBrowserController</string>
                                      ]
                                      these have no ill effect, but add either of the others and you beach-ball...
                                      %(#00BF00)[<key>OpenInspectors</key>
                                      <array>
                                      <string>PagePanelController</string>
                                      <string>LayerPanelController</string>
                                      <string>StyleBrowserController</string>
                                      <string>SoftenPanelController</string>
                                      <string>EntityInfoController</string>
                                      </array>]
                                      They actually fork the main Thread into a timer loop to make the thumbnails and will do that even if the ruby has run before you open the Inspector. i.e run test code without, then zoom, orbit, make new geometry, etc... turn on 'Components' or 'Outliner' and you'll get a beach-ball.
                                      If 'Components' is run first 'Outliner' opens straight away.

                                      john
