	* If your CAD file has many (eg. thousands/millions) of overlapping polygons, the conversion software can take a long time to process the file. This looks like the tool's write-head writing / pausing / writing / pausing as the tool waits for more data from the computer during the "converting/exposing" operation. You can '''"merge" the polygons''' in KLayout prior to writing to reduce this. We found that a 1hr exposure → 10min with this method!		* If your CAD file has many (eg. thousands/millions) of overlapping polygons, the conversion software can take a long time to process the file.

	* Write time scales directly with write area. If you have large areas to expose with small unexposed regions in between consider using a negative PR and an inverted CAD file to reduce write area.		* Write time approximately scales directly with write area. If you have large areas to expose with small unexposed regions in between consider using a negative PR and an inverted CAD file to reduce write area.
			* Since the raster scan does the fast-scan in the Y-axis, and the tool generates vertical "stripes" for each patterning region, if you have large vertical regions with no exposure, you can reduce write time by ensuring there are no objects in those vertical area - the tool will skip those Stripes entirely. Even a small dot in a vertical Stripe area will require the tool to write the entire stripe.
