[Bacula-users] Long despooling time

Hello all,

I have problem with long despooling time from spool directory (stripe
of 2 luns from netapp filer. Write speed ~120MB/s ) to MySQL database.

Despooling of ~80GB of data takes about 3,5 hours when backing up
50000 of small files. System with storage daemon runnig is Solaris 10
with 2 CPUs ( 8 cores ) and 8GB of RAM

Is there any way to speed up despooling ?
