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.

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 Andreaù On Sat, Sep 1, 2018 at 10:34 PM Ashley Mort <ashley_c_m...@raytheon.com<mailto:ashley_c_m...@raytheon.com>> wrote: 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?

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?

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?
