[mapserver-users] ESRI binary grids RRD files ?

[Sebastian E. Ovide]

Frank,

I've left those RRD and I suspect that for some reason the pyramids are not
read... In fact the performance is very good for zoomed in views (street
level)... but it is very slow for zoom out views (city level)...  and I can
see the IO working very hard...

is there any way to see if MapServer/gdal is reading the pyramids correctly
?

thanks
