Tp whom it may concern . . .

I’ve recently been optimzing some MapServer layer MapFiles in our system for 
TIGER based centerline data to take advantage of the newer capabilities of 
MapServer.  The MapFile I’ve been working on recently  was just over 10 years 
old!!  Anyway, lot’s of new stuff for optimizing the Mapfile and I wanted to 
pass the results by the list to see if there is anything I may have missed.

For long time list users, you may remember my post in the past about setting up 
a “googlish” type layer style for MapServer way back when.  This is my 
refactoring of that MapFile to the new look and feel of the Google style(s).

This mapfile has mutiple CLASSes with many STYLE settings per CLASS.  So it ens 
up a bit complicated.

I’ve also switch all data sourcing over from SHP file to Postgres/PostGIS as 
well as consolidating the all the DATA connection calls into a single call.  
While the old file ran very fast, this one comes back almost instantly now, 
even for very large images.

Here are a couple of fragments of the MAPFILE that I’ve currently set up, and 
just looking for thoughts on improving it even more.

Sample output is here:

 and the fragment below is for the Interstate roads, darker yellow color and 
Hwy Shields..

Thanks
