[richfaces-issues] [JBoss JIRA] Commented: (RF-7272) Sorting in ExtendedDataTable is slow, especially under IE 7

[Arne Könnecker (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-7272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12469448#action_12469448 ] 

Arne Könnecker commented on RF-7272:
-------------------------------------

Deactivating the column menus lead to improved performance of the rerendering. But still the reendering of the table with 30 rows and 10 columns is felt as pretty slow.

My time measure has reduced from around 800ms to around 300ms. But this is only the request not the rendering within IE 7, which seems to be slowest part.

> The rendering of an ExtendedDataTable under IE 7 after clicking on a column for sorting is very slow.
> See http://livedemo.exadel.com/richfaces-demo/richfaces/extendedDataTable.jsf?c=extendedDataTable&tab=usage for testing
> What can improve the performance of such a table? Deactivation of column menus? Deactivation of drag & drop functionality? Or is the
> rendering process slow due to not fix column width and height?
