Could you look at mysql server please? Its CPU usage, disk usage,
swapping, memory usage...

Here are examples from my backup server with mysql:

1) 18,688,335 files in 37 minutes, which is ~ 500,000 files per minute:

   03-Nov 08:37 backup-sd: Sending spooled attrs to the Director.
   +Despooling 6,159,834,448 bytes ...
   03-Nov 09:14 backup-dir: Bacula backup-dir 5.2.12 (12Sep12):

2) 309,936 files in time is under 1 minute:

   02-Nov 14:00 backup-sd: Sending spooled attrs to the Director.
   +Despooling 86,532,417 bytes ...
   02-Nov 14:00 backup-dir: Bacula backup-dir 5.2.12 (12Sep12):

I think that there are three key settings on my server:

1) MyISAM tables
2) delay_key_write = ALL in my.cnf
3) Database on SSD

Best regards.
