1: 750,000 points is not really that large. Rather than spend the time
establishing a makeshift cluster, just load the data on your beefiest desktop
and view it there. I just created a 800,000 point data set on my laptop
and it works reasonably well.<o:p></o:p></span></font></p>

number 2: If you insist on using client server, just use a single
(multiprocess) pvserver instead of the dual pvrenderserver/pvdataserver. See
the discussion on the Wiki: <a
