Well stated Mr. Morissette !<br><br>

I agree with some of your points, but I strongly disagree on the
"low<br>
performance and numerous security holes"... you also forgot to
mention<br>
(in the pluses) reliability/stability and connectivity with other<br>
systems via protocols such as OGC WMS (client and server), and<br>
on-the-fly access to various data sources such as SDE, PostGIS, 20<br>
raster formats and half a dozen vector formats.<br><br>
I'm actually glad to hear that you have been able to combine easy<br>
configuration and application development, flexibility, high
performance<br>
and affordable price into a single product... it's a huge step in
the<br>
right direction since none of the current map server offering could
do<br>
*all* of that until now AFAIK... not even MapServer which I have to<br>
admit requires some skills and some time before you can take full<br>
advantage of all its features. This is not sarcasm... if what
you<br>
pretend is true then I'm impressed! But I won't believe until I
see<br>
it... <br><br>
Does your note imply that Manifold IMS will deliver better
performance<br>
(and stability) than MapServer? Other than the mythic belief that
CGI<br>
is slow, MapServer is actually the fastest fully featured web map
server<br>
I've seen until now... yes CGI overhead exists but it is minimal<br>
compared to the time to render maps based on hundreds of Megabytes
or<br>
even Gigabytes of data (which MapServer can accomodate amazingly
well<br>
thanks to its high performance internal architecture!).<br><br>
Anyway, I'm looking forward to see a Manifold-based website that
can<br>
beat Jean-Francois Doyon's Election application which served 80,000
maps<br>
from a single Linux box on elections day last fall while sites based
on<br>
other webmapping servers all went down. There is no cache trick
here...<br>
we're talking about real maps drawn and served. Combine that with
a<br>
pool of servers with load balancing and the possibilities are
unlimited<br>
(and the price hard to beat!).<br><br>
80,000 maps per day on a single server is acceptable performance to<br>
me... if Manifold IMS beats that then I might even consider digging
out<br>
our old Manifold license and upgrading to see it by myself.<br><br>
Best Regards,<br>
