nsslapd-import-cachesize

database cache size for import

Description

This performance tuning related attribute determines the size of the database cache used in the bulk import process. By setting this attribute value so that the maximum available system physical memory is used for the database cache during bulk importing, you can optimize bulk import speed. If you attempt to set a value that is not a number or is too big for a 32-bit signed integer, you receive an LDAP_UNWILLING_TO_PERFORM error message with additional error information explaining the problem.

Note:

A cache is created for each load that occurs. For example, if the user sets the nsslapd-import-cachesize attribute to 1 GB, then 1 GB is used when loading one database, 2 GB is used when loading 2 databases, and so forth.

Ensure that you have sufficient physical memory to prevent swapping from occurring, as this results in performance degradation.
