Hi,
I got interested in comparing the performance of using tiled geotiffs with
overviews v.s. JPEG 2000 images. So far I have set "DEBUG ON" in map object,
named a logfile in the web object, made two layers from geotiffs and JPEG 2000s
and set "DEBUG ON" for the both.
Now when I send requests to Mapserver I get new lines to logfile, but I do not
know where I should find the time that it takes to render the layer. Here is an
splitted example of the lines I am getting to the log:
Mon Apr 03 13:08:52 2006, #this is obviously date and time
2732, # no idea about what this is
1xx.xx.xx.xxx, # IP address of the requesting computer, I believe
Tifspeedtest, # name defined in the mapfile
3, # no idea about this, but value seems to be always "3"
2539375.000000 7220000.000000 2545625.000000 7225000.000000, # extents of
the request
-1.000000 -1.000000, # no idea about these two either
Geotiff , # names of the requested layers
normal execution # the result
Now I wonder if this is the way to do this, and if so, then what I should think
about the numbers. I wonder also why I get two lines per request if I send
"&mode=map&layers=Geotiff" request through browser, but nothing at all if I am
sending WMS "GetMap"requests with the browser for the same layer, even if I do
get the map.
Might there be some good document about using debug available? Those I have
found helped me this far but not any further.
Regards,
