Hi Olivier Nicole,

I read you post on yahoo. I use amanda with an DLT 8000. This drive has
an LVD interface and is quite fast. The optimal block size for this tape
is 64k. So after some experiments I changed the default tape block size
in amanda.h from 32k to 64k. This speeds things up a lot. I now get
around 5700 kB/s (without hardware compression) from holding disk to
tape.

amanda.h:

/* Size of a tape block in kbytes.  Do not change lightly.  */
/*  #define TAPE_BLOCK_SIZE 32 */
#define TAPE_BLOCK_SIZE 64
#define TAPE_BLOCK_BYTES (TAPE_BLOCK_SIZE*1024)
