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

[Andrey Chorniy (JIRA)]

    [ https://jira.jboss.org/browse/RF-7272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12566208#comment-12566208 ] 

Andrey Chorniy commented on RF-7272:
------------------------------------

In my case filtering and sorting is external (in DB), but it really doesn't help - reRendering take time and traffic and that reduce user experience.

I really like the extendedDataTable, but it's really huge (re-rendering takes much time because of large size of the HTML/javascript (data-tranfer/client-side processing)
for example for a row with 10 columns and only 1 data-row the size of http-request (reRender the table) 55091 bytes (could be a bit reduced, but still around 45000)
extended-data-table.txt (55091 bytes)
extended-data-table-with-menu.txt (206170 bytes)
row.txt (2213 bytes)

It would be really nice to have a possibility to disable Drag-And-Drop and any other features. so, introducing more parameters like "enableContextMenu" (enableColumnMove enableColumnResize) - they could be truned on manually by adding some controls on the page and re-rendering the table in "design" mode)
As well as just looking for the way to simplify/reduce the size

> 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?
