Sketchup 8 faster than sketchup 13?

SU8 and SU2013 were much of a muchness on speed. SU2014 is much faster.

But Aerilius is correct that you need to compare apples to apples; check you have identical Observers attached in both versions before testing.

however some plugins will crash SU2014 in SU2013 all be good.

can you give an example?

this might help to find an explanation

Does anyone have examples to follow this discussion?

Runs with 25 fps in Sketchup 8 and sucks with 5 fps in Sketchup 2014 ...

Comparison for SketchUp 2015 ?

tt_su

No code examples? Or anything we can run to test?

I tried my Stair Maker plugin with the last 5 versions of SU on Windows 7.

I asked it to build a 360 degree curved stair with housed stringers and 56 Risers, 50 progressive flare (forces 50 unique treads and 50 unique risers) Each tread flare inreased by 5 mm.
The stair had 2 of the most complex rails that I provide. So there are 392 curved and twised sections making up the 2 rails.

SU 7: 44 seconds
SU 8: 42.5 seconds
SU 2013: 34.3 seconds
SU 2014: 32.3 seconds
SU 2015 64 bit: 33.5 seconds

Here are the parameters of the stair.
You can see the progressive flare.

glro: you seem very quick to judge things you perhaps do not understand.

The purpose of having 2 locations, is that one is a global, shared repository, another is a per-user repository.

OK, now i understand the interest of a global repository: it doesn't need the session name
C:\ProgramData\SketchUp\SketchUp 2015\SketchUp\Plugins

so it might be easier to find when installing a plugin

maybe ...

but still, if a plugin needs special components to be installed, it still has to be done in the program files folder; so it still needs administrator rights

the component folder should be outside the program files folder also

Shut down the external ruby pipeline and hire a bunch of ruby coders. Now that would be a diabolical means for Trimble to make money wouldn't it?

What does the code do?
Apart from pure mathematical calculations, programming languages can also have side effects and interact with the environment (and such side effects make things hard to reproduce and bugs hard to discover).
Although the ruby version is maybe still the same, the SketchUp environment is changed and performance is affected by entity creation (which then can even call observers of other plugins) or interaction with the user interface.

from SU profiler result, the program mainly spends time in this type of operation
"Sketchup::Entities#each"

would you say that this includes these lines of code?

for e in entities
    if e.is_a? Sketchup;;ComponentInstance
          status = selection.add e
    end 
end #for

do you suggest that some plugins (as mine ...) running slower would be the consequence of an intentional reduction of capacity for ruby programs to interact with sketchup?

The profiler (plugin!) requires quite some understanding of what it does, and how meaningful the result is — even for more advanced developers this profiler in its current state is not that much helpful. That it spends time in each doesn't tell much without decomposing what it does inside each.

There is no "external" ruby pipeline.

thank you for the answer

so no clue from profiler plugin
and no conspiracy theory

and what about the incidence of the previous model opened? i did notice that the time necessary to proceed on the basis of fixed parameters, may vary according to the previous model opened

No.

Phew, I was worried for a moment.
