Description
Linux host/WinXP sp3 guest
When running an old 16 bit visual basic application under ntvdm performance is unacceptable. The processor use never drops below ~30%.
When using the application performance is dreadful. Screen paints can be watched and any operation involving IO is stunningly slow.
Machine is a conversion of a vmdk, IO APIC still in use (though configured as such).
