The question about why the pvserver processes are always at 100% CPU comes up frequently on the mailing list (such as http://www.paraview.org/pipermail/paraview/2008-December/010338.html). I've added some information to the Wiki about it to provide an explanation: http://www.paraview.org/Wiki/Setting_up_a_ParaView_Server#Server_processes_always_have_100.25_CPU_usage

I have read that paraview runs serial, pvserver parallel, so I started the server by mpirun -np 4 pvserver and connected through X. Everything seems to work fine. But there are two strange behaviours I have noticed: 1. CPU usage on workstation is almost 100% on three of the four cores although no client is connected (when I type mpirun -np 3 pvserver there are 2 out of 4 running at 100%; with -np 2 only 1). I have noticed this using MPICH2 and OpenMPI. 2. When I now start a client process the server uses only one core (-np 4/3/2/1). Why? Does MPI not work on multicore systems as on multiprocessor systems or is this a Paraview issue?
