Out of professional curiosity and to possibly help future students: could you tell us a little about the system you’re running this on? Things like the base OS, the amount of RAM, the type and speed of the processor and your storage type (hard disk vs SSD). We’ve seen some less-than-nice behaviour with the VMs if the host-system is older/slower.
