I remember I wanted to check in on resource usage. So, here we are 75 posts in, with many edits. Running htop, I wasn't able to catch it using using more than 1.5% of one CPU. And, the amount of resident memory it seems to be using, right after startup, is around 1.5GB of RAM. Java is a bit of a memory hog for sure.
