Here is quick test I ran on the performance of my current setup. If
anyone can see some things I need to do I'd appreciate it. A couple
things that we're kicking around is breaking the layers (Outdoor
Rural/In-Vehicle Rural Hwy/In-Building Suburban/In-Building
Urban/In-Building Dense Urban) down to county level sizes, create a
tileindex of groups of counties, then create a tileindex referencing the
county group tileindex. I really don't think this would improve
performance unless the common zoom/extent was at a county level. The
other thought is loading all of these shapefiles into the Oracle
database as spatial data. I've gotten a request from the higher-ups to
increase the performance of our MapServer. The server we're running on
is a 2.8GHz XEON w/ 3GB of RAM. Thinking that maybe an increase in RAM
might help us out too. At this point we're pretty invested in the
Chameleon framework so a move to another application framework is not
really an option. Thanks.
