Hi all,
I am running Geoserver 2.12.1 on Windows (Java8, 32bits, JAI & JAI
ImageIO installed).
I have set up an ImagePyramid wich works OK, but performance is not as
good as what I expected.
From the logs, the time taken between the parsing of the request and
the end of the granules collection is OK (~ 200ms to query the index
stored in a PostGIS DB, collect 6 granules, which are 1000x1000px TIFF
files with LZW compression).
But then, it takes almost 1 second for JAI to merge these granules into
the final PNG.
I have enabled multithreading on this layers which helped quite a lot,
and disabled JAI_IMAGEREAD which helped a little.
The log files shows nothing special happening, so I guess it's just the
process that is not very fast : https://pastebin.com/EH8K6tUJ
I have left the defaults in JAI and Coverage Access settings.
Is there anything I could try to make things faster ?
Thanks a lot !
