Yes, I see bunch of following messages and it looks like all most all time 
being taken to service up the WMS GetMap request is spent in the 
“org.geoserver.jai” processing:

Subject: Re: [Geoserver-users] GeoServer 2.15.1 - WMS GetMap request taking 
extreme long time

Any hints about data format, raster or vector, data coordinate reference 
system, does it change when you zoom in or out or is it always slow?

Are their any repeating stack traces in your GeoServer log?

Hello GeoServer community,

After upgrading GeoServer from 2.14.1 to 2.15.1, I am experiencing extremely 
longer time to get valid image from WMS GetMap request.

I am using WMS version 1.1.1, GetMap request and below is the sample request:
[host_url]/geoserver/[workspace]/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image%2Fjpeg&TRANSPARENT=true&LAYERS=[layer_name]&exceptions=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326&STYLES=&WIDTH=443&HEIGHT=768&BBOX=28.564453125%2C-67.5%2C106.435546875%2C67.5<https://nites-gis.dev.net:8443/geoserver/imagery/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image%2Fjpeg&TRANSPARENT=true&LAYERS=imagery%3AEMETEO.IR.1km&exceptions=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326&STYLES=&WIDTH=443&HEIGHT=768&BBOX=28.564453125%2C-67.5%2C106.435546875%2C67.5>


Any suggestions/ideas how to debug this issue or configuration/settings that 
can speed up the process are greatly appreciated.


Thank you.
