There is the parameter "speed" but it is not currently used by AMANDA.

I don't know if the number of parallel lufs-mounts relates to
performance ... AFAIK it would not be necessary to have them all
mounted, only the vtape that is currently requested.

Vlad, create an archive containing :

- your config-files (usually /usr/local/etc/amanda/<myconf>)
- the corresponding log-files (/usr/adm/amanda/<myconf>) and
- the debugfiles (/tmp/amanda)

and send it to me off-list.

Have you already tried to use the lufs-mount-option "--channels=X" ?

Best regards,
Stefan G. Weichinger.
