This paper addresses the issue of the relation between the system efficiency and the individual performance with in adaptive competing systems. The adaptive competing systems are modeled by mix-game model which is an extension of minority game (MG). In mix-game, there are two groups of agents; group 1 plays the majority game, but the group 2 plays the minority game. The average winnings of agents can represent the average individual performance and the volatility of a system can represent the efficiency of the system. It is found the correlations between the average winnings of agents and the means of local volatilities are different when agent history memories change under their different configurations. This paper also gives some suggestions for designing complex competing systems.
