#1976 closed defect

Optimize lookup of EPSG projection codes — at Version 3

Reported by: dmorissette Owned by: dmorissette
Priority: high Milestone: 5.4 release
Component: WMS Server Version: unspecified
Severity: normal Keywords: projections
Cc: warmerdam, jmckenna

Description (last modified by dmorissette) 

A few weeks ago I was doing some benchmarks with MapServer 4.10 on a mapfile
with about 10 layers in it and replacing the 10 "init=epsg:xxxx" defns with
native PROJ.4 definitions made the WMS GetCapabilities requests go from 3
hits/seconds to 12 hits/seconds (4 times faster!).

Since EPSG codes are used a lot by all OGC services, optimizing the EPSG lookup
(or caching them at a minimum) is something that would be very valuable for all
OGC service users.
