Dynamically modifying the allocation of branches of a directory information tree to directory servers, based on the real time volume of requests processed for a specific branch at a particular directory server. In particular, a Master Server (MS) utility calculates and stores branch access numbers for each server in the form of decaying averages. The MS utility maintains these access numbers within a database table. The MS utility determines if branches are transferred to a new master server by evaluating these access numbers within pre-set transfer criteria, which include a set of Boolean conditions. That is, transferring a branch to a new master server is dependent on the branch access numbers of the prospective master server candidate satisfying a set of Boolean conditions. Once the MS utility determines that these Boolean conditions are satisfied, the MS utility transfers the branch to that new master server.
