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

I've developed an static version application based on<BR>MapServer CGI, which
means I just use pure HTML tages for the GUI, even <BR>without JavaScript code
snippets to validate forms.<BR><BR>I have about 20 map layers to display
according to different map scale<BR>(ussing the MAXSCALE, SYMBOLSCALE AND
LABELMAXSCALE), there are no data<BR>classifications within a layer object,
the status of all layers are set as <BR>default.<BR><BR>I've made a test on a
standalone MapServer (XP system), every request takes<BR>about 3 second.
Obvioursly it's not fast enough for a web application, since<BR>there may be
many users requesting the server at the same time if the <BR>application is
published on the web.<BR><BR>Is MapServer really so slow? can anybody give me
some ideas?should I modify<BR>the mapfiles?<BR><BR>I am wondering whether the
following solutions will work:<BR>1. define every layer as a seperate mapfile,
and combine them together by <BR>request<BR>2. turn off the
non-displayed layers off on the fly<BR><BR>are these possible to speed up
MapServer performance?</BLOCKQUOTE></DIV><BR></BODY></HTML>
