Hi, Maybe you should test directly with the MapServer cgi to know if it is due to pmapper or MapServer / PostGIS.
Concerning PostGIS, there are few improvements to do : - indexes : http://postgis.refractions.net/docs/ch04.html#id2819937 - FAQ : http://postgis.refractions.net/docs/ch04.html#id2820900 - performance tips : http://postgis.refractions.net/docs/ch05.html And for MapServer : - optimizing vector data sources : http://mapserver.gis.umn.edu/docs/howto/optimizevector - optimizing raster data sources : http://mapserver.gis.umn.edu/docs/howto/optimizeraster - try to see if the class expression in each layer are not too long to evaluate and to draw Thomas Cristian Rougier a écrit : > Dear Ivan, thank your you answer, no, i not use this, im converted the esri > shapes > To postgis with shp2pgsql util and load this to the database. > > Do you know any doc for ST_simplify function or tutorial? > > Any other tip? > > Regards. > Cristian > > Tecnología y Programación en Internet. > http://www.lainfo.com.mx > [EMAIL PROTECTED] > > http://www.sistemas-geograficos.com > > Emails muy pesados a: [EMAIL PROTECTED] > Tel:(++5255) 8589-1554 > Movil, Nuevo! : 04455-1770-9888 > > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ivan Mincik > Sent: lunes, 18 de febrero de 2008 9:59 > To: pmapper-users@lists.sourceforge.net > Subject: Re: [pmapper-users] Pmapper / mapserver optimization > > Do you use ST_simplify function for smaller scales? > > > On Monday 18 February 2008 16:52, Cristian Rougier wrote: > >> Dears, i have a pmapper-3.2-beta2 running in a hostgis linux 4.2 (64 bits) >> The application run with 64 layers ( in a postgis database). >> >> The server are a dell 2900 ( 2 xeon dual core ) with 4 gb ram , 16 mb video >> ati es1000. >> >> >> >> But I see the system slow, in full extent the layer are too slowly to load. >> >> >> >> I understand that when less layers are active (or more little are the >> extent) more faster are the system. >> >> >> >> But I need to put more layer on this system. >> >> >> >> >> >> I need the best optimization for this, if you please do you know any doc or >> Say me recommendations for max speed of layers display ? >> >> >> >> I will up the shared_buffers of postres database to 500Mb. >> >> >> >> The video memory (or adapter) are sensitive?
