Slow read write in fluent on two machine cluster
 

I am using fluent on a two machine cluster. Both having intel xeon 2ghz 14 core dual processor. 256 GB RAM. Both machines are connected via qlogic 10 GBe connection. My problem size is 26M~.I am having problem while reading the case file. It takes about 2 hrs to partition the mesh. What can I do to improve the performance?
