Category: main tag library Group: None >Status: Deleted Resolution: None Priority: 5 Submitted By: fabrizio giustina (fgiust) Assigned to: fabrizio giustina (fgiust) Summary: Performance enhancements (patch) Initial Comment: Performance enhancements >From dev ml (Todd Benge) > There are several steps we are taking to improve the overall > system performance, one of which was to look at the displaytag source > code. In doing so, we were able to make a couple of significant > changes that have made a major impact on overall performance. So far > the changes we’ve made have not had any impact on functionality but we > do not use the el tags or velocity templates. We’ve tagged all of the > changes in the source files with my name (Todd) so that you can > evaluate the changes. The attached jar file includes the source files > changed as well as the Borland Optimizeit profiles taken before and > after the work was completed. You should see that the processing time > spent in the tag libraries and main JSP is significantly reduced. > This is mostly due to caching of previously reflected methods and the > removal of the iteration in the doAfterBody of the TableTag. If the > changes look reasonable, we’d be happy to commit the changes back to > the community. The two authors of the changes are Todd Benge and Matt > Green. ---------------------------------------------------------------------- >Comment By: fabrizio giustina (fgiust) Date: 2004-09-22 14:21 Message: Logged In: YES user_id=798060 moved to the new jira tracker http://jira.codehaus.org/browse/DISPL-11 ---------------------------------------------------------------------- Comment By: habsuda (habsuda) Date: 2004-07-27 11:11 Message: Logged In: YES user_id=846835 Hi, I found the problem but I don't know how to solve it. It happens only when some static cells are used. example-imp-objects.jsp is this case. I tried merge it with b3, rc1 and rc2 and all do the same. Could someone fix it, I realy need this performance patch.
