I realise a very strange behaviour on ALL VBox systems we run on FreeBSD since 9.0 that do have more than 4 physical cores. No matter how many cores I delegate to a guest system (Windows 7), the 6 or 10 core XEON systems (12 or 20 logical cores) starts getting irresponsive, dramatic slow and within the Guest and outside USB mice become highly jumpy and not very responsive. Compared to a reference box running the very same OS revision, but with a low-end 4-core XEON with only 4/8 physical/logical cores, the system is dramaticallt slow. A system update of the guest was performed within 2 minutes on the small XEON e3-12XX Haswell (16GB RAM), it is still running after 75 minutes on one of the 6-core systems (technical specs as shown above) (with 32GB RAM). Is there a known issue (couldn't find something useful via Google) with FreeBSD? Regards, Oliver
