Can you specify better how slow it is, if it is constant or what it depends on? For me it takes to render one layer full screen 1-2s and it seems to be constant. Each draw runs external executable which reads GRASS data and QGIS reads the data from its stdout. That is the right way GRASSers recommend/allow. It adds some overhead for starting the executable, I am no sure how fast is passing data via stdout. It could be probably improved using the same like identify is using, i.e. keep the GRASS module running and send data requests to its stdin.
