Why each option
In the `slapd.conf` file, `cachesize 1000000` defines the maximum number of entries to be stored in the OpenLDAP server's entry cache.
For OpenLDAP database backends, the `cachesize` directive specifically configures the maximum count of directory entries that the server will hold in its memory cache. Setting it to `1000000` means the server can cache up to one million entries for faster retrieval, thereby improving query performance.
The `cachesize` directive specifies the number of entries, not the size in bytes; memory usage is dynamic based on entry content.
The `cachesize` directive specifies the number of entries, not the size in bits.
The `cachesize` directive sets a maximum limit, not a minimum, for the number of entries.
The `cachesize` directive specifies the maximum number of entries, not the maximum size in bytes.
