Reprojecting with Gdalwarp vs native MapServer

[Jan Hartmann]

Hi,

I have noticed that reprojecting layers on the fly in MapServer is much 
slower than creating a new file with gdalwarp and using that one in 
MapServer. With a PHP-MapScript program MapServer took two to three 
times as much time as gdalwarp, despite the fact that gdalwarp requires 
an extra read/write operation to disk. Is it possible to let MapServer 
use gdal's warping engine when gdal is available?
