Hello,

Using 7.5.0.3, restoring 1m+ files in a single directory, obviously this would take hours/days (bpdbm just runs forever) to start so what I am doing is splitting it into chunks and that is helping (it works) but was wondering if anyone on this list knows of any special:

DIRECTIVES for bpdbm in the bp.conf to optimize/help speed it up for restores?

It seems there are some interesting ones:

IS_ASCII_CATALOG_FILE_FORMAT

SKIP_NOTIFICATION_FOR_UNIT_TEST

INSIDE_CATALOG_CLEANUP

CLEANUP_KILLED_BY_SIGNAL

CATALOG_BACKUP_PARENT_JOBID

INSIDE_ASA_BACKUP

NB_BPDBM_TEST_DELAY_SOCKET_CLOSE

KEEP_EXISTING_DOTF_DURING_IMPORT

NB_BPDBM_ALIVE_LOCAL_TIMEOUT

There are more as well, does anyone have any tips to improve restore performance of lots of files?

Justin.
