Did you have a "muscle" config for mysql ( based on my-huge.conf ) for your
my.cnf server conf ?
For the director on which mysql reside and that is doing only bacula we
increase quiet a lot the proposed value
to make mysql more happy with insert and query for backup.
a building tree for a typical session for 650,891 files and 245Go take less
than 2 minutes
on a AMD x2 6000 proc with 4Go ram.
Mysql reside on a single sata 7200trms disk.
here our values
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
#skip-locking
key_buffer = 512M
max_allowed_packet = 2M
table_cache = 512
sort_buffer_size = 4M
read_buffer_size = 4M
read_rnd_buffer_size = 16M
myisam_sort_buffer_size = 128M
thread_cache_size = 12
query_cache_size= 84M
# Try number of CPU's*2 for thread_concurrency
thread_concurrency = 4
character-set-server=utf8
default-collation=utf8_general_ci
[isamchk]
key_buffer = 512M
sort_buffer_size = 512M
read_buffer = 4M
write_buffer = 4M
[myisamchk]
key_buffer = 512M
sort_buffer_size = 512M
read_buffer = 4M
write_buffer = 4M
skip-innodb
skip-bdb
Last point we don't use the batch-insert mode.
Hope this help you a bit.
