Thanks for your reply!

I have 4096 mb ram in my Virtual Machine, unfortunatly i dont know what binaries are in my Virtualbox, I only changed Cores from 1 to 2 in my Virtualbox Menue.

I didnt lock the Solver, i printed it out in the terminal and saved a screenshot of the runtime :/ what i can say from the outwritten data, that it takes nearly constant 5 minutes for each second when running in parallel, when running normal on one core it takes at the start 3-5 min and later only 1 min for each second.

Edit: PAE is disabled in my Virtualbox, could that be the Problem?

Thank you for your help,

Kind Regards

Daniel
