How many resources it uses? Can it be shared withother applications?

I am considering reinstalling YACY on an existing VM that is used as my BOINC server, and a Plex server.

But, I was wondering how much resources YACY uses? Is it light on the resource usage?

I am also wondering what hardware are using other peers.
Actually I have it installed in a KVM machine with Debian but I have only allocated 1 core and 2 Gigs of RAM but it can be scaled up anytime.
For HDD space I have 40 GB but I presume this is not enough since 200k entries have already 10 GB .
