Dear all, I work with Windows with Qgis 3.34.13-Prizren. I have a Qgis project destined to be shipped on a tablet for the field (Qfield). The project contains a polygonal layer of 3427 objects (file shp). There are many columns with different types. There also relational values / joins setted for this form. So the project also includes .csv files (for relational values).
The problem : the opening of this table attribute takes up to 40 seconds. I spent time to identify where the problem may come from. At one time I thought for joins/relational values. Or also CSV format. As we can see here : https://gis.stackexchange.com/questions/423054/what-is-slowing-qgis-the-most-when-opening-form After several hours of investigation, the source of the problem seems to come from 4 columns (string) for strore the pictures. After removing those 4 columns of the form, the opening time of the table become normal. I have tried to "play" with the parameter for this form attached tool, (as for example relative/absolute path size of the images, etc.). But in vain. Have people ever been confronted with this problem/limitation/problem of table opeining performance regarding the attribute form design? Linking with attached tool for image/picture ?
