[Gimp-user] slow rendering of images

[Anthony ODoibhailein <info adevlinvisual com>]

Hello,

I am a new user of GIMP and have been quite impressed with the range of features and usability. However I am 
working on a large banner and am finding the rendering of the image is extremely slow.
I have just upgraded my mac from a powerpc to a 12 core intel machine and am not appreciating a great speed 
benefit so far due to this slowness of rendering.
I appreciate that it may well be down to the setup. I have the RAM set to 10Gb in the GIMP preferences which 
I had thought sufficient to show an improvement but its not given much of a boost.

Is there anything ~I should be installing or tweaking to get the best out of GIMP when working with large 
format images?

Hope to hear from someone soon.

Hope this makes sense as its my first foray into this mailing list!

Thanks

Anthony
