Hi Andrea
I’m trying to install the native JAI in my environment using the geoserver
directions. http://docs.geoserver.org/latest/en/user/production/java.html
In the GeoServer Service Status panel the “native jai” and “native jai imageio”
settings are still false. Should they be true if it is set up correctly?
Thanks.

The performance for bilinear didn’t improve with jai-ext enabled. I’m going to
try tuning geoserver and the garbage collection. Then I’ll profile the code to
find the bottleneck. If there are any other thoughts please let me know.

Hi Ashley,
as said before, with JAI-EXT enabled I'd expect bilinear scaling to be slower
(while for example we have reports
that bicubic warp is faster, it depends on the operation), but since you have a
test ready, try it out and let us know how it worked?
All the "native accelerations" will be off obviously, as those require "native
jai" to be installed and
jai-ext to be turned off.
Basically, keep the defaults that you have
Cheers

Interesting info there that I was unaware of with the jai-ext startup
parameter. We have a bunch of ImageMosaic layers served as PNG with a default
GeoServer 2.13.0 install (no native JAI installed).
Would the recommended setting generally be to use
-Dorg.geotools.coverage.jaiext.enabled=true then leave the defaults in
GeoServer Image Processing settings like below?
PNG Encoder: PNGJ based encoded (recommended)
JPEG Native Acceleration: off
Mosaic Native Acceleration: off
Warp Native Acceleration: off
JAI/JAIEXT Setup
JAIEXT Operations
all
JAI OPERATIONS
none

Hi,
yes, the performance drop looks bad. Have you enabled jai-ext in 2.13.x? (it
does more work, more comprehensive
ROI handling and NODATA Handling which was not there before) so for a simple
scale it's slower also in my local tests,
that said we are running all production envs with jai-ext enabled with no
complaints (probably because bottleneck are elsewhere,
network storage, JPEG2000 decompression and the like).
If you did not enable jai-ext in both environments, did you install native JAI
in both?
Cheers
Andrea

Hello
I was recently doing some performance tests on the v2.5 GeoServer.
Jmeter Test configuration:
The tests were for WMS 1.3.0 getMap requests for a 74x96 deg of a GeoTiff.
The interpolation is set to bilinear and each test run is performed 100 times
in a loop.
Each loop is paused for 200-500 milliseconds before sending out the next batch
of concurrent requests.
Example request:
https://localhost:8443/geoserver/test/wms?layers=test:grid&width=512&height=666&bbox=73.0,-19.0,147.0,77.0&srs=CRS:84&format=image/png&version=1.3.0&service=WMS&request=GetMap.
To be candid, The average response time is much worse in v2.13 compared to
v2.5. I ended up updated v2.13 to use Marlin but the performance is still not
as good as compared to v2.5. Attached are the before/after updates.
I know there were a lot of updates between the versions but is there a global
setting, cache, or configuration property that I should be looking into?
