For R, that doesn't strike me as particularly much. - The point here is that the method being used by default requires storage of a 10000 by 10000 matrix - it's not really an issue of whether 10000 is particularly much "for R". There is a cut and paste-able example for getting around this at the end of the help file for gam()... gam will be *much* faster and *much* less memory intensive if you use it.
