If OP enabled gzip then this 36mb would be 13mb.

If OP reduced 30 months of posts in rss to 12 months then this 13mb would be 5mb a day.

Yeah, but also... if RSS readers behaved correctly, it would be 512 kb. (170 kb with gzip, if she didn't enable it like you imply – I'm too lazy to check, but I assumed it was on.)

I think making clients behave correctly is much more sustainable solution, although we could do better than doing so at the cost of the end users.
