it is an issue in the creation of the netCDF file not the extraction.
when you write successive variables to a netCDF file, a temp file is
created in which the current file is copied over too. This copy and recopy
takes progressivley a large amount of time.

here is a web page that explains this:

you may be experiencing slow down from the grib read as well, so there
could be two factors against you.

you may want to pre-define the file size etc. this can help with speed:
