+# WARNING: Before tuning the following parameters, _PLEASE READ_
+#   http://www.openldap.org/faq/data/cache/1075.html
+
+# Set the database in memory cache size.
+#
+# set_cachesize <gbytes> <bytes> <ncache>
+#   Sets the database in memory cache size. 
+#   Database entries and indexes will be stored in this cache to 
+#   avoid disk access during database read and write operations. 
+#   Tuning this value can greatly effect your database performance. 
+#   The parameters are:
+#      <gbytes>: The number of gigabytes of memory to allocate to the cache.
+#      <bytes>: The number of bytes of memory to allocate to the cache.
+#      <ncache>: The number of cache segments to use. If this value is set to 
+#          0 or 1 then Berkeley DB will try to allocate one contiguous section 
+#          of memory for the cache. If this value is greater than 1, the cache 
+#          will be split into that number of segments.
+#set_cachesize   0       52428800        0

+# Sets the database startup flags.
+#
+# set_flags <flag>
+#   There are various flag options that may be set. The DB_TXN_NOSYNC flag 
+#   tells the database not to immediately flush transaction buffers to disk. 
+#   Setting this flag can help speed up database access during periods of 
+#   database write activity BUT at expense of data safety. Enable it only
+#   to load data with slapadd, while slapd is not running.
+#set_flags       DB_TXN_NOSYNC

+# Set the maximum in memory cache in <bytes> for database file name caching.
+#
+# set_lg_regionmax <bytes>
+#   This value should be increased as the number of database files increases 
+#   (tables and indexes).
+#set_lg_regionmax        1048576
+
+# Set the maximum size of log files in <bytes>.
+#
+# set_lg_max <bytes>
+#   Logs will be rotated when <bytes> amount of data have been written to 
+#   one log file. This value should be at least four times the size of 
+#   set_lg_bsize.
+#set_lg_max              10485760
+
+# Set the in memory cache for log information.
+#
+# set_lg_bsize <bytes>
+#   When <bytes> amount of logging information have been written to this 
+#   cache it will be flushed to disk.

+#   database files. This both improves reliability (for disastrous
+#   recovery) and speed of the database.
