Without quilting, and with regular netCDF, the head processor will gather and write out data. With quilting, N number of processors will be set aside to do data gathering (while the head processor writes). For a large number of grid points, in theory this can improve wallclock time. However, this is not a tested or developed feature, and we really do not recommend doing it, as it can very often cause problems.
