Something wrong with Steemd.exe

I've just realized that my steemd eating more than 2GB ram, is this normal @ned @dan? Because my ubuntu seed-node which is serving 100+ peers only consuming 600-1GB ram.

Steemd is v0.12.2 compiled by @bitcube,
This is strange because from changelogs:

• Performance improvements especially in memory management
• Hard limit to address oversized blocks and transactions

Memory leaks? or just me?
