When the amount of pixel data exceeds this limit, GIMP will start to swap tiles to disk. This is a lot slower but it makes it possible to work on images that wouldn't fit into memory otherwise. If you have a lot of RAM, you may want to set this to a higher value.
Ma thèid àireamh nam piogsailean thairis air a' chrìoch seo, tòisichidh GIMP air leacagan a shuaipeadh dhan diosga. Bidh seo mòran nas slaodaiche ach leis a sin, is urrainn dhut obrachadh air dealbhan a bhiodh tuilleadh 's mòr mu choinneamh na cuimhne agad. Ma tha mòran RAM agad, faodaidh gum b' fheairrde dhut luach nas motha a chur an-seo.
