Grid Massaction Bandwidth Usage of setGridIds

[amenk]

If a grid supports massaction / select all, all the ids of all pages of a grid are included in the page in the setGridIds call (see Mage_Backend_Block_Widget_Grid_Massaction_Abstract). If the shop has for example 10000 products this is around 50 KB of data that is included on every page of the product listing.

To improve performance, the currently included grid IDs could be stored in the session server-side and the mass action select all could reference to this session storage for example by an unique hash.

For now, the issue is not scheduled for implementation. However, there are two related technical tracks: backend grids extendability & modularity, and performance. You will be notified, as soon as there is any activity on the internal ticket.
