Enterprise Vault slow retrieval time from Data Domain

Hi,

We are in the process of migrating our EV archive data from EMC centerra to EMC Data Domain.

Running some archive retrieval tests we are seeing very long retrival times up to 45 seconds compared with 1-2 seconds on the centerra.

Anyone archiving to Data domain can you let me know what your retrival times are so we have some idea if there is something wrong with our configuration or the performance is expected with a DD ?

THanks,
