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.
Pixel datuen kopuruak muga hau gainditzen duenean, GIMPek mosaikoak diskoan trukatzen hasiko da. Motelagoa izan arren memorian doitzen ez diren irudiekin lan egitea uzten du. Ordenagailuak RAM memoria ugari izanez gero, handiagotu hau balio altuagora.
