[ https://issues.jboss.org/browse/DROOLS-4735?page=com.atlassian.jira.plugi... ] Jozef Marko updated DROOLS-4735: -------------------------------- Description: There have been reports that the performance of the DMN editor's grids does not scale. On examination performance for anything other than simple examples is pretty dire.. something is seriously wrong. On closer inspection the following issues were found: - Multiple {{NodeMouseDownHandler}}, {{NodeMouseMoveHandler}} and {{NodeMouseUpHandler}} are registered because multiple {{DMNGridLayer}} are (incorrectly) instantiated due to a flaw in {{GridLienzoPanel}} and {{GridLienzoScrollHandler}}. - Calls to {{GridWidget.getHeight()}} and {{GridRow.getHeight()}} can be _very_ expensive for due to the dynamic calculation in {{ExpressionEditorGridRow}} and {{LiteralExpressionGridRow}} rows. h2. Manual Acceptance test Environment: wildfly14 with following memory settings: {{JAVA_OPTS="-Xms64m -Xmx1024m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=1024m -Djava.net.preferIPv4Stack=true"}} h3. GDT - Merge view (/) - Pinned mode (/) - Change column width, save and reopen (/) - Search the table (/) - Scroll the table (/) - Edit the cell (/) - Reorder columns (/) - Reorder rows (/) h3.
