Abstract: Under different background stream，topologies and classes of service，Fiber Channel（FC） network performance has been tested.Graphs of relationship among throughput，delay and workload have been given in different traffic pattern.Through analysis the conclusions are presented.The message delay of fabric and class 3 of service of FC is respectively smaller than Arbitrated Loop and class 2 of service，and maximal throughput of the former is bigger than latter；The research on the message delay in FC reveals that the timely delivery of the message can be achieved in the network if the accumulated load is less than 50% of maximal throughout in a uniform traffic pattern.
