[Vm-dev] Re: Too many full GCs in Cog/Spur ... while just drawing GUI ...

[marcel.taeumel]

As for the number of full-GCs tested with:

DisplayScreen depth: 32 width: 1024 height: 768 fullscreen: false.
{String. Morph. Socket. Rectangle. Form} do: [:ea | ea browse].

x := Smalltalk vmParameterAt: 7. "num full GC since startup"
[ActiveWorld imageForm] benchFor: 5 seconds.
(Smalltalk vmParameterAt: 7) - x

Here are the results:

5.0 All-in-One --> 22 full GCs
4.6 All-in-One --> 0 full GCs
Trunk --> 14 full GCs

I do not claim that these performance issues are solely due to GC.

Best,
Marcel
