Hello, yesterday using a Sage session I had open for a few days was very slow. Computations were not finishing in reasonable time and I thought I needed better algorithms. Today, when I restarted my session, these computations finished in reasonable time. One which did not finish in 5 minutes yesterday finished in 90 seconds today. I'm on Windows 10. Is there a reason for why a Sage session can be "burdened" by being open for a long time?
