Q: Why are File Transfers slow ?

A: This problem is usually caused by one or more of the following:

- Network tuning option sare not set in HPSS.conf and/or the host kernel

- Wrong host network interface is being used for the transfer

- The buffer size is too small for the HSI or HTAR client

- The HPSS Mover buffer size is configured too small

- The Virtual Volume block size configured for the HPSS storage class is too small 

or too large to support effective striping

- The local filesystem is unable to keep up with HPSS
