We have just seen this in the XeroSpace Advanced - 181.214.149.204 server:

We had about 20 players online, CPU use was ~40% (the way windows measures it, I believe)
It is however modded and running among others: Unique Xsotan Artifacts, Better Docking, Bigger Threats, Out of Sector Production, Carrier Commander.
(I fixed the problems in Bigger Threats here, as it is not currently maintained and had problems: https://github.com/Joeppie/AvorionModFixes/tree/master/BetterThreats_v1.1/scripts )
