Speed up dbf reading when the target charset is not multibyte
-------------------------------------------------------------
Key: GEOT-2683
URL: http://jira.codehaus.org/browse/GEOT-2683
Project: GeoTools
Issue Type: Improvement
Components: data shapefile
Affects Versions: 2.6-M2
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 2.6-M2
Decoding the bytes of the dbf row into chars is one of the most expensive
operations the shapefile reader is doing (when the dbf is opened at all, that
is).
This is due to che usage of the Decoder class, which is pretty generic.
A custom code path that just assumes the 1-1 byte-char correspondance is quite
a bit faster (15-20% overall while reading statepop.shp)
