I just built HDF/netCDF (the mfhdf directory in HDF3.3r3) and 
ran NCTEST on my DEC Alpha OSF box.  NCTEST completed 
successfully, but took over 3 minutes, while NCTEST from the 
standard Unidata Netcdf (v 2.3.2) took only 2 seconds!!

When I did "ps" during the lengthy NCTEST run with HDF/netCDF,
it reveals that NCTEST is spending nearly all of it's time as
a uninterruptible sleeping process.  


Is this normal behavior for NCTEST with HDF/netCDF?  Has someone
run NCTEST with HDF/netCDF and obtained decent results?

Thanks,
