I have eliminated thousands of points on a map exported to Illustrator. The redraw time is still 10-15 seconds after each click, even in Outline mode. The file size is not that large. Any suggestions welcomed.
I have a K4000 Quadro card, Xeon e5-1650 v2, 850 Evo SSD and 16 GB of DDR3 with decent timings. A redraw of any vector in the thousands of points gets laggy. I try to keep my pathing as simple as possible with the fewest points. Also make sure that if you are working with a decent GPU that you have updated drivers and that GPU acceleration is turned on in Illustrator preferences.
Access the Document Raster Effect Settings in the drop-down Effect menu:
Reduce the Resolution:
The lower you go, the more busted up it starts to look, but the quicker it gets.
It's useful as a temporary workaround.
I asked a similar question and this solution worked well for me.
