GD vs AGG performance...

[John Cole]

I'm just going by the tuning info reported by mapserver, but there is a
noticeable difference between them.

Try:
MS4 (MS4W 2.2.2) total time: 0.250s
http://map.uai.com:28080/cgi-bin/mapserv.exe?map=/mapserver/tiger/tiger.map&mode=browse&layers=bound+hydro+landmark+roads+roads_anno+city+hydro_anno+landmark_anno+landmark_point

MS5 AGG (MS4W 2.2.6) total time: 1.266s
http://map.uai.com:28080/cgi-bin2/mapserv.exe?map=/mapserver/tiger/tiger5.map&mode=browse&layers=bound+hydro+landmark+roads+roads_anno+city+hydro_anno+landmark_anno+landmark_point

MS5 GD (MS4W 2.2.6) total time: 0.250s
http://map.uai.com:28080/cgi-bin2/mapserv.exe?map=/mapserver/tiger/tiger5gd.map&mode=browse&layers=bound+hydro+landmark+roads+roads_anno+city+hydro_anno+landmark_anno+landmark_point

Except for GD->AGG (and the debug difference between 4 and 5), the map files
are identical.

(BTW, these are using the same html template, so if you navigate, you won't
be using the same MS/renderer combo).

Is there something else that needs to be done for AGG to perform similar to
GD?
