[Qgis-developer] Why is scrolling in the attribute table so slow?

when copying/pasting rows from the table of attributes to another
program (ex: calc) the column with the geometry is also included (it
would be good an option to avoid that).

This seems to me (but I can be very well wrong) this is the cause of the
very slow scrolling and selecting in the table of attributes: if the
geometry are complex, even with a few rows (regardless if it is postgis
or else) it becomes painfully slow.
