Hello,

I have a performance problem, with the "grib_nearest_find" function, between version 1.9.0 and 1.10.0 (10 minutes versus several hours).

The problem lies in the file "src/grib_nearest_class_reduced.c" because if I replace this file from version 1.10 with the version 1.9, the problem disappears. The problem seems to come from repeated call functions "grib_get_double" to get the first and last file longitude. I think if the GRIB file used is the same, it is not necessary to repeat these calls.

If you need further information, do not hesitate to contact me.
