Ticket #1501 (closed defect: fixed)
very high cpu utilisation if usb 2.0 is enabled
|Reported by:||strangebird||Owned by:|
After upgrading from VirtualBox 1.5.6 to 1.6.0 on a Mandriva 2007.1 host, I noticed that the cpu utilisation for the VirtualBox process was near 80% when the guest OS (Windows 2000 Professional) was running - although the guest OS showed an utilisation of less than 10%. Before upgrading I was used to an cpu utilisation for the VirtualBox process of less than 15% (guest cpu utilisation + maximum of 5%). Disabling the usb 2.0 option gives again an cpu utilisation of 15%.
