Juanma,
What version of the ecw libraries are you using? There was some
discussion about the speed of the ecw library on linux vs windows with the
ecw 3.3 sdk -RC 2 in this discussion thread
http://lists.maptools.org/pipermail/gdal-dev/2006-August/009795.html . The
final 3.3 ecw SDK may have fixed this.

I

>Did anyone have the same problem?
