[ http://issues.apache.org/jira/browse/DERBY-938?page=all ]Dyre Tjeldvoll updated DERBY-938: --------------------------------- Attachment: get.xhtml Attaching a spreadsheet that shows the reduction in CPU resulting from optimizing getContext(String) for StatementContext and ExecutionContext. The load is single record select, 100000 records in the table, pageCacheSize=10000, 10 sek warmup time, and 10 min running time. The measurements are obtained using Sun Performance Analyzer 7.4 While I have accepted the fact that the getContext(String) part of the patch will not make it into Derby, I would still like to document that there IS a perfomance issue lurking here, and I would encourage "the folks that have been working on the product for nearly ten years" to think about how it can be fixed without violating other important design criteria.ContextManager needs to be optimized ------------------------------------ Key: DERBY-938 URL: http://issues.apache.org/jira/browse/DERBY-938 Project: Derby Type: Improvement Components: Performance Reporter: Dyre Tjeldvoll Assignee: Dyre Tjeldvoll Priority: Minor Attachments: derby-938.diff, derby-938.html, derby-938.stat, derbyall_report.txt, get.xhtmlContextManagers are used extensively, particularly to get access to ExcutionContexts and StatementContexts. Optimizing this access should improve overall performance.
