One alternative to allowing LO to create a new user installation each
time (which will indeed be slow) is to create a fresh user
installation once, save it somewhere as a template, then make a new
copy of the template directory each time - a file level copy should be
considerably faster.
You can accomplish this simply in Python using shutil.copytree()
Some sample code appended below - this is hacked out from a previous
project, and may or may not represent best practice as to how to do
this, but does work.
