摘要： A method and system for predicting the performance of a multi-tier computer software system operating on a distributed computer system, sends client requests to one or more tiers of software components of the multi-tier computer software system in a time selective manner; collects traffic traces among all the one or more tiers of the software components of the multi-tier computer software system; collects CPU time at the software components of the multi-tier computer software system; infers performance data of the multi-tier computer software system from the collected traffic traces; and determines disk input/output waiting time from the inferred performance data.
