Hi, when I try to open attribute table which contain 31 000 entities it takes a lot of time because of charging only 100 entities per seconds so if I open table with a lot of entites I can't open table quickly. If I stop the process I obtain a table with for example 800 entities and I can't using field calculator because if I do that Qgis crash. In 2.2 version the open attribute table in the same shape are almost instantaneous. I don't know if it normal but it's not really helpfull to work.

of course it is not the expected behavior but also it does not happen in a clean installation or may be is something that is data related. Please attach a sample of your data.

I find why I have a problem to open attribute table, it's because there is a csv join within use cache option. If I join the csv in cache there is no problem but if I join the same csv dynamically the attribute table is very slow to open. I joined to you a csv file which could be join at corine_land_cover data if you want trying.
