It varies from application to application.  Wine itself may not have any inherent design with parallelism for performance, but the applications you run may be written to split work into threads or processes which Wine creates and then linux schedules across cpus/cores. As demonstrated in the sample program I posted.

If you wanted to speculate on why one particular application runs slow you'd need to profile it with oprofile or some other profiling tool and it will give you an indication of where time is spent.  I don't think it helps to generalize.
