IndexedFidReader reads the index file inefficiently
----------------------------------------------------
Key: GEOT-2401
URL: http://jira.codehaus.org/browse/GEOT-2401
Project: GeoTools
Issue Type: Improvement
Components: data shapefile
Affects Versions: 2.5.4
Reporter: Andrea Aime
Assignee: Jesse Eichar
Fix For: 2.5.5
The NIO buffer allocated is just a handful of bytes, this results in a lot of
OS calls.
The inefficiency was introduced in GEOT-2050 to fix a bug. At the time I
checked and it did nto seem to make a difference, benchmarks I run today show
it actually causes the GeoServer performance over the FOSS4G 2008 benchmarks to
significantly drop (57 req/s as is, over 85 after patching to read a buffer
1024 times bigger).
I also made sure the bug reported in GEOT-2050 is fixed, the test cases
introduced there still pass (that required some modifications other than just
changing the buffer size of course)
