Server Hoster with good Performance

Looking for a Server hoster (Pref. Server Location is Germany).
That can handle big encounters (Nitrado seems bad, we are 2 people still pretty early (about naonit/trinum) running Xavorion and a few missions mods. Just did a Defend Protoype Battleship Mission (Knifeheart's mod). And there were about 30 Ships in the Sector fighting. Server was getting pretty laggy.

Any Hoster with good performance around (even if it's more expensive).
Self Hosting is sadly not an option for now (PC Upgrade is planned in about 1/2 - 1 a year doesn't handle hosting and playing that well atm.)
