[ITK-dev] [ITK-users] Speed Issue

[Matt McCormick]

Hi Xiaopeng,

In general, most algorithm implementations are multi-threaded and
intended to use all CPU cores. There may be some implementations that
should be multi-threaded or there may be some implementations that
could be improved in their thread utilization.

There are ongoing efforts to improve performance - your participation
is welcome.  See:
