This would make a huge difference both in file size (i.e. I/O time),
memory usage and performance. Also, since you have your own reader,
make sure that there isn't a bug/performance bottleneck there. Are you
using a custom reader for ensight as well? I don't know whether
EnSight preloads everything. ParaView won't so the timing you have
includes reading.
