Not much info to determine the problem.
[1] 200MB is not particularly large. Nor is 40-50 variables.
[2] How did you generate the weight file?
Did you write the NCL script or did you use the template at
http://www.ncl.ucar.edu/Applications/ESMF.shtml
Example 25
This would generate a weight file which you could use for
all subsequent regridding via:
http://www.ncl.ucar.edu/Document/Functions/ESMF/ESMF_regrid_with_weights.shtml
[3] How are you writing the netCDF file? NCL allows 2 different ways
to create netCDF: one is the 'simple but, possibly, inefficient'
method; the other requires predefintion of the output
netCDF file's contents.
http://www.ncl.ucar.edu/Applications/o-netcdf.shtml
While 40-50 is not a large number of variables per se, When you
use the simple method this could be slow for assorted reasons.
[4] The following may be useful to look at.
(a) generate weight file
http://www.cgd.ucar.edu/~shea/se2fv_esmf.genwgt.ncl
(b) use weight file generated in (a) to regrid multiple
variables and write to netCDF via simple* method
http://www.cgd.ucar.edu/~shea/se2fv_esmf.regrid2file.ncl
(c) same as (b) BUT uses 'efficient (predefine)' method to
write netCDF. This requires a double pass over the data
(i) predefine output file's contents (structure);
(ii)write regridded variables to predefined file.
