Creating items under a parent simultaneously shown in several grids is unbearably slow (between 30 and 45s)

 

Steps (ideally, this would be done with my DB as a DB of a few MB doesn't really do anything significant, but still, it gives an idea):

- sample DB

- open welcome grid

- reattach 3 grids to the work space : MusicLibrary, Appointments, To-Do's

- copy-paste those grids in the welcome grid

- Mark the infoQube item in the welcome grid and add it as a children of an item (anyone) in all 3 other grids (MusicLibrary, Appointments, To-Do's) : use "add marked item as children"

- Expand the hierarchies in each grid, and use word wrap for good measure.

- Now, if you add items in the Welcome grid, under the "infoQube" item, you should notice a little delay (on my computer at least) and you should see the items appearing in all grids simulteneously (even if grid auto update is off), with a slight delay obviously

This delay isn't there when grids *aren't* side by side (+ showing the same stuff). 

This delay happens in a DB of a few MB... You need to multiply it by 550x to get an idea of how it feels on my DB

 

I noticed that it doesn't seem to matter whether grids are visible or not. As soon as they're loaded, the problem arises, even if they're hidden/not visible.

 

(Just in case that question arises... Why would someone create items under a parent simultaneously shown in several grids ? simply because the parent/item is used in different contexts and needs to be viewed in such different contexts at the same  -- e.g. reference used in several parts of the same/different documents/projects .)
