When building my master thesis, I've found that the size of the produced PDF differs if I use Tex Live on Ubuntu compared to MiKTeX on Windows; for the latter, the size is about 50% greater (from about 600KB to some 900KB).
I'm just curious why this might be. I mean, the look and layout is the same (as far as I can tell, at least). So where do these extra 300KB come from?
Okay, so on the MikTeX I got
pdfTeX 2.9.4225 (1.40.12), and on TeXLive I got
pdfTex 2.3-1.40.12. The two versions are available below:
