Thanks for the answer!
Yes, its PNG
It’s a cascaded WMS consuming a PNG image itself. The GetMap request to the
underlying WMS is logged at the next step.

Hi
I wonder what Geoserver makes during “setting up image” during GetMap call to
WMS-endpoint. See logfile snippet:
INFO | jvm 1 | 2015/03/31 14:09:58 | 31 mar 14:09:58 DEBUG
[org.geoserver.wms.map] - setting up 4000x3250 image
INFO | jvm 1 | 2015/03/31 14:10:06 | 31 mar 14:10:06 ERROR
[org.geotools.map] - Call MapContent dispose() to prevent memory leaks
INFO | jvm 1 | 2015/03/31 14:10:09 | 31 mar 14:10:09 INFO
[org.geoserver.wms] –
Ah, the time you have between those two log lines is:
* setting up the image
* read the data
* paint the image
* encode the result in png
So... it's everything, not just allocation of the image, which is actually just
a split second.
In a image such large png encoding is likely going to dominate the overall
request time (just guessing here, you did not say which image
format you're using).
Cheers
Andrea
