Does Hearthfire increase anyone else's save game file sizes massively? I noticed I was getting some lag issues since installing Hearthfire today (not so much lag, but intermittent pausing.) In particular when I hit F5 the game freezes for about 15 seconds before saving. I checked my save files and any save that was made before Hearthfire are around 11-16 mb, but anything altered after Hearthfire was installed are around 56mb. Note that I have not bought any land let alone begun construction yet.

Hmm... I've been playing a still relatively new character who is currently level 19 and my savegame size increased by about 700kb after installing Hearthfire (7.7MB total size). Nothing like the massive difference you've seen.
