| + | ==== When dragging a table into a screen...Do you query all records ==== | ||
| + | |||
| + | We have lazy loading everywhere and per default we only load the records that you see on the screen and some more to fill a buffer. We usually load records for about 100 milliseconds but at least the visible amount. The scrollbar shows that more rows are there. When you scroll down, more rows are loaded. The speed depends on the database query/performance and network speed. | ||
