A reason for the service being so slow the first time it is called may
be the on-demand libraries loading. But for this to take a long time,
the native skin library would have to be stored on a really slow storage
device, or compressed and the processor you are using being a really
slow one. Anyway, you do not tell us on what architecture you get this
issue? What processor are you using? Where is the library stored?
