That works now — thank you!
With the change:
185552 entries processed in 108.2 s
Before the change:
185552 entries processed in 220.1 s
The exact commands I’m running:
cd Dokumente/Guix/guix
git checkout master # with the change
./pre-inst-env guix environment --ad-hoc jupyter python-ipython
python-ipykernel -n
time guix build /gnu/...-manual-database.drv
git checkout 97bf46e64c11c64a968fdb833983ede6bdafbc00
./pre-inst-env guix environment --ad-hoc jupyter python-ipython
python-ipykernel -n
time guix build /gnu/...-manual-database.drv
So I also see roughly factor 2 speedup, which means a limit to 4 threads
should work.
(what I saw is that I only see the …manual-database.drv before I build
it, after it’s built, I no longer see it in the environment output)
How do I get the defined limit of cores and threads?
Best wishes,
Arne
