Thanks for the reply.
Then something is wrong with my setup. Even without changing anything a run
of sage -b takes more than 4 min for me. I'd now run multiple builds `sage
-b` directly without any changes in between and all apps closed etc. The
output is attached below. Maybe the reason is that I'm using WSL 2 on
Windows?
Regardless of these problems (which are apparently specific to my
situation), don't you think it would be worthwhile to extract the library
part of sage? I think this would reduce the overhead needed to develop code
for sage.
Best
