<br>
I am finding that when the datasets are small, I have no problem starting<br>
multiple gdal_rasterize processes (using python).<br>
<br>
If my datasets are large (I'm trying to create rasters with millions of<br>
pixels), I'm finding that I can only start one gdal_rasterize process at<br>
once, or sometimes, after a couple have started the rest refuse to start.<br>
<br>
RAM shows usage below 50%, and CPU usage is also below 50%.<br>
<br>
I can't figure out whether this is a gdal_rasterize thing or not?<br>
