FOSS gamedev and creative worlds

I am considering using Minetest as a conference competition (details withheld, sorry) and was wondering how many players a server can host? I see numbers in the 10's. what about around 100? All players will be an a local LAN so bandwidth should not a consideration.

I have a quad core machine with 8 Gig RAM, but again, does the Minetest server make use of the extra cores? (the server may be running other services as well).

Thanks in Advance

50 should work, but you may need to adjust these settings to get Minetest to make use of more cpu cores
