The performance project
This wiki page is the collaboration entry point for the OOo Performance project.
For questions and discussions, please use the new mailing list from the performance project: dev@performance.openoffice.org
When you plan to file an issue with regard to performance, please make sure to add the keyword performance
The official (incubator) project was started February 2009, but there have already been a lot of activities in this area in the past, so some of the information here (especially on the linked wiki pages) might be outdated.
This page will be cleaned up soon.
To-Dos
Probably a lot - please continue here.

Calc
The DPL extension (version 2.3.0) produced a SQL statement which lead to a Database error.
The reason may be an internal error of DPL or an error which you made,
especially when using DPL options like titleregexp.
Query text is:
SELECT DISTINCT `page`.page_namespace AS page_namespace,`page`.page_title AS page_title,`page`.page_id AS page_id, rev_user, rev_user_text, rev_comment, rev_timestamp FROM `revision` AS rev, `page` INNER JOIN `categorylinks` AS cl0 ON `page`.page_id=cl0.cl_from AND (cl0.cl_to='Calc') INNER JOIN `categorylinks` AS cl1 ON `page`.page_id=cl1.cl_from AND (cl1.cl_to='InProgress') INNER JOIN `categorylinks` AS cl2 ON `page`.page_id=cl2.cl_from AND (cl2.cl_to='Performance') WHERE 1=1 AND NOT (`page`.page_title LIKE 'Calc/InProgress/Performance') AND `page`.page_is_redirect=0 AND `page`.page_id=rev.rev_page AND rev.rev_timestamp=( SELECT MAX(rev_aux.rev_timestamp) FROM `revision` AS rev_aux WHERE rev_aux.rev_page=rev.rev_page ) ORDER BY rev_timestamp DESC LIMIT 500 OFFSET 0
Error message is:
Unknown column 'rev_user' in 'field list' (127.0.0.1)
