Iirc it used to sit around 300MB. And yeah, my balance is low. I very very rarely see it staking though - pretty much always at Stake 0.00 GRC. Although I might just not understand how it works... =)

debug shows it signing for blocks every 1-2 seconds but not much else. debug2 has it listing contracts in project and whitelist count multiple times per second. debug2 also claimed on startup that I had a Mag of 00, client shows 25 and NN shows 30. /shrug
