OpenMP allows GraphicsMagick to scale nicely with multiple CPU cores and had ran similarly between the native and KVM implementations, there was only a small drop in performance for the three tests carried out -- HWB Color Space, Local Adaptive Thresholding, and Resizing.

The traditional DES and Blowfish performance with the popular John The Ripper program only suffered minor performance setbacks under KVM.

The multiple sequence alignment using MAFFT performed just a few seconds slower under a KVM guest OS.
