Poor servers performance on some games

Hello. Question to organizers.
In this game http://theaigames.com/competitions/warlight-ai-challenge-2/games/55437b8135ec1d06ec71dfe3 in turn 12 from dump I can see that bot waste on turn more then 4 seconds.. But on my local machine it takes near 140 ms. I don't belive that your severs and my computer has so different hardwere. More likely your server is overloaded in background with some other work and therefore in some games performance so bad. Could you confirm that assumption? And could you guarantee that at least for finals server machine will work only on execution of one game, and on nothing else?
