Re: How to run multiple instances of Writer simultaneously?

Thank you Tor for the clarification.

What I want to achieve is to use the Python UNO bridge to access multiple Writer documents at the 
same time.

If that can be achieved by running a single LO process (soffice.bin) then that works for me: 
  - How does that approach scale when I open many Writers? (See this post re performance and 
scaling: https://forum.openoffice.org/en/forum/viewtopic.php?f=6&t=74002 )
  - Should I keep the LO process alive over long periods of time and then open/close Writer 
documents as needed? (See this post re the Office Server mode: 
https://forum.openoffice.org/en/forum/viewtopic.php?f=20&t=75523 )

If I need to spawn processes with separate “user installation” directories, are you talking about 
the -env:UserInstallation command line argument?

Thank you!
Jens
