Tips for MapServer

Fill out your server (and service) metadata

Speed up services by:

- providing explicit extents- spatial indexes- providing appropriate caches

Other Pro-tips:http://www.slideshare.net/gatewaygeomatics.com/mapserver-protips

Tips for GeoServer

Fill out your server (and service) metadata

Disable any services not being used

Serve from formats with spatial indexes

Tips for ArcServer

Compress database

Enable WMS capabilities

Set min/max instances to # of servers
