> A basic operation like adding a single attribute call many times methods like
> parsing the DN, or lookup the database.
> For instance, in the following test, where the attribute Description is added
> to an existing entry, there are :
> 26 alls to DnParser("cn=tori amos,ou=system") method,
> 8 calls to DnParser("ou=services,ou=configuration,ou=system") method,
> 8 calls to DnParser("ou=configuration,ou=system") method,
> 8 calls to DnParser("ou=system") method.
> For information, on my computer, 1 000 000 parsing of the DN "cn=tori
> amos,ou=system" is done in 24,490s, so doing it 26 times cost around 0,6 ms.
> Here are some logs demonstrating this issue :
