Subject [jira] Updated: (DIRSERVER-175) Basic operations are very costly
Date Fri, 10 Feb 2006 05:23:02 GMT
     [ http://issues.apache.org/jira/browse/DIRSERVER-175?page=all ]

Alex Karasulu updated DIRSERVER-175:
------------------------------------

    Component: ldap

> Basic operations are very costly
> --------------------------------
>
>          Key: DIRSERVER-175
>          URL: http://issues.apache.org/jira/browse/DIRSERVER-175
>      Project: Directory ApacheDS
>         Type: Bug
>   Components: ldap
>     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 :
