Hi Matthew,
the ticket I was referring to is this one:
https://osgeo-org.atlassian.net/browse/GEOT-5391
The ticket links to https://osgeo-org.atlassian.net/browse/GEOS-7464 which
was not closed,
Simone says there is still some work to do, but I do not have specifics on
it.
You might want to comment on that ticket and attach a way to reproduce the
slowdown (data, style, request)
Cheers
Andrea
