nsslapd-cache-autosize

This performance tuning related attribute which is turned off by default, specifies

value will be lower. Setting the value to 0 turns off the cache autosizing and uses

nsslapd-cache-autosize-split

This performance tuning related attribute specifies the percentage of cache space to
