Hi my friends,
I am really very thankful for all your information, I am a newbie in
MapServer.
here is the data amount that I am using for the application:
(all the source data is MapInfo format, and what I calculated is the ".MAP"
file)
1. boundaries -- 388 KB
2. forests -- 9163 KB
3. lakes -- 26 KB
4. city parks -- 25 KB
5. settlement -- 2279 KB
6. rivers -- 1653 KB
7. road networks -- 56370 KB
8. railway -- 1343 KB
9. train station -- 27 KB
10 bus station -- 2 KB
11. tourist centers -- 9 KB
12. theaters -- 6 KB
13. shopping center -- 7 KB
14. city location -- 9 KB
*****
and here is how I am symbolizing the layers, mapfile for all these layers:
***

***********************
is it still possible to speed up my application?
****
the system parameters of my application:
Windows XP professional
MS4W 4.8.1
data source -- MapInfo data
*--only CGI parameters are used,since it is a pure static version with HTML,
is it possible to develop a pure static application based on MapServer, even
in conjunction with PHP/MapScript or Chameleon?
thanks for any clues.
