different, especially on the local network, since map images are always
generated in 32 bit color before being saved out to gif or
png.</SPAN></FONT></DIV>

class=321304013-01062006>I tried your site and searching for CASTILLO did not
take 12 seconds, it took about 2 not counting the time it takes to zoom the map
to that feature. Selection in the AJAX viewer is done on the server side, so it
is normal for it not to be instantaneous -- it has to redraw the map with the
object you selected highlighted. </SPAN></FONT></DIV>

time on the server, for some reason. What is the data format for your layers --
are they SDF or SHP?</SPAN></FONT></DIV>

<DIV></DIV>Hi, <BR><BR>I'm developing a gis based in MapguideOS. Here you can
find a temporary example of my work:<BR><BR><A

</U>Very slow. Maybe tweaking some file or parameters can help. The image in the
cache show me a filesize between 80Kb with <I>gif</I> and double with <I>png.
</I>So what's the server does? I can't understand this hole of time.<BR><BR>I
hope ideas, comments and
conclusions.<BR>---------------------------------------------------------------------
