<p>Well - I think Richard beat me to the punch. I'd convert it to
Geopackage and make sure it has a spatial index as a first shot. <br>

<p class="MsoNormal">We need your help with this app issue. My
user is trying to generate vector tiles of a polygon shapefile
of census tracts for California. When she has successfully run
this command before, it took a consecutive 36 hours with no
other applications running for the process to complete. Most
of the times she has tried to run this, QGIS crashes, and
sometimes her computer completely crashes.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Many other commands take a very long time.
She tried to do a spatial join yesterday of about 400 points
with the census tract shapefile, which took 2-3 hours.<u></u><u></u></p>

<p class="MsoNormal">When I connected to the computer, there was
an error message related to memory. She has 16GB of memory,
and when she runs the command, it uses around 95 to 98 percent
of the memory resources.<u></u><u></u></p>
