LandHouse is a new distributed storage system that is based on Pastry protocol. LandHouse is often under a high degree of data access when used, but it does not work very well. This paper designs a new system LandRoom based on LandHouse, the new system changes network topology and concurrent reading and writing strategy of LandHouse and uses a suitable load balance algorithm that is called by heap-based dynamic threshold mixed load balance algorithm, these will improve the throughput of the whole system. We report on extensive experiments with the strategy and new algorithm. The results illustrate the benefits of our approach over the original system.
