GIF compression

Hay
Sorry if this should not go in programming but not sure where else to put it

I have a GIF file of a roadmap which is 16k in filesize

if i make the picture 4x as big (ie double each dimension) the filesize increases exponentially ie. more than x4 , i would have thought it would be non exponential as GIF is very good at compressing large areas of the same colour which is what roadmaps normally have (mine has).

WHAT HAPPEN ?

You're aware that they are still slower to parse and require an XML parser while a binary format would be a million times better? And all this just for marketing. It's XML, so it must be good. I'm surprised they didn't call it something-ML (ML sells well), although they made sure to include the word "scalable", even though all vector graphics are scalable, just to confuse managers.

Oh, so it's not entirely developed by faildobe (faildobe's website was like I INVENTED SVG LOL), well, that's good news I guess, but it still fails for XML. SVGZ will be better, but it's still piss slow compared to a binary format.
