Juanma,

I've never run into this myself.  Do you also see a similar delay when
using gdalinfo to report on the ecw file, or gdal_translate on a small
file?  I'd suggest trying to debug it at that level rather than within
mapserver if you can reproduce the problem there.

Also, you might want to contrast with FWTools which also includes ECW
support.

Best regards,
