I honestly don't know what happened, I zipped it up before i uploaded the file and i even downloaded it to see if it works and it did, so i have no clue how that happened but i'll just re-upload it.

Eh it happens when you upload directly to this site from time to time so no worries there
Any event let's see what this contains
Save01.rvdata2
Size: 5.46MB
Falls within the average 2-6MB
(Though I guess I should have specified Each so that's a fault on my end for not clarifying)
Your Auto Save looks like it's the same thing (Same Size & Time Stamp) so not worried about that.
Two that stand out are:
$game_map contains the current map you are on so yeah the World Maps are rather big so the size is understandable
None of the Events contained within look like they are malfunctioning so they aren't needlessly hogging RAM
Note: You can reduce the Save File Size by avoiding saving on the World Maps though that only would effect how long it takes to Save/Load
$game_variables contains all the major variables the game tracks. That's roughly 5,000 with Towerfag making some of those into Arrays so it's even larger than that. Nothing wrong with it though.
The other ones aren't really worth mentioning as they are a significantly smaller.
For Performance you can try:
Cheat Code 517634 = Choose the weather
Try Clear and see if you get a performance boost as weather effects while pretty aren't that useful
Doesn't look like you have many wars going on as I only seen two skirmishes
If you did I would have suggested Cheat Code 255148 = Sets PEACE
Hopefully the Options Menu Towerfag has in the works let's you turn on Dash by default since the Knight walking everywhere just makes him seem more sluggish than he really is. While not a performance issue try Dashing from place to place
