Basic operations are very costly
--------------------------------
Key: DIRLDAP-61
URL: http://issues.apache.org/jira/browse/DIRLDAP-61
Project: Directory LDAP
Type: Improvement
Reporter: Emmanuel Lecharny
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 :
