This is not exactly a netCDF4-python issue (so feel free to close), but I thought users of this repo might be interested to test out my latest project, h5netcdf, an alternative interface for reading/writing netCDF4 as HDF5 files directly via h5py.

Feedback would be greatly appreciated!

My initial performance tests suggest that it generally has very similar performance to netCDF4-python, except for multi-threaded writes to a single file, for which it is about twice as fast (I tested against v1.1.6). I haven't tested compression yet.
