I have tested the latest wine.
I've noticed that it can go to slightly slow to really slow, but any way causes audio dropouts, since an application called scrollkeeper-update and xorg's cpu utilization use almost 100% cpu at some point.
Try loading a vst inside eXT or making any file browsing operation.
