Making more memory available to VM on OS X.

Hi,
I'm doing some fractal drawings which requires a great number of iterations and point drawing.
Once the given fractal set is rendered Pharo becomes very sluggish. Is there a way to allocate more memory to the VM upon starting it?
thanks

This is strange. I can understand that pharo takes time to compute a fractal but I do not see why it would be sluggish after.

Thanks for the attachments I will take a look at them.

The time it takes to render the fractal is not the problem. But after that, if I want to drag or resize the window the fractal has been draw into, the sluggish begins. Even with the fast dragging option checked. Also, closing and opening other windows become sluggish.

thank

take care

Re: Making more memory available to VM on OS X.

Probably because you should cache the result you get and not redraw it all the time.

You should control when you want to redraw it. So your Morph should hold a form or something like that.
