I am trying to speed up export of a region to stl format, and I noticed
in g-stl.c that there is a hard-coded ncpu=1 . Does changing this to
2 or 4 speed up the stl conversion (if there are 2 or 4 cores
It looks like there is a command line option to set ncpu , but lower down in the code it is hard-coded to 1 .
