[UMN_MAPSERVER-USERS] mapserver postgis connection

[Frances Collier]

Hello,   I’ve been trying to find out what exactly Mapserver gets back from Postgis when querying the tables. I haven’t found this to be documented anywhere. Does Postgis return a shape file, layer, or simply data rows? The reason I’m asking is that I noticed a huge time difference between connecting to Postgis and simply calling the shape files – with the Postgis being significantly slower   I’d appreciate any knowledge, advice, and/or direction.   Thank you, Frances Collier
