No, out of the box 9.1 doesn't include the patch.  Tried adding it in and no 
difference.

I've done some testing running the queries with "distrib=false" and can see the 
query itself runs fine it's just the call to the instance and the response is 
slow.

Something to do with Jetty?

Could it be related to 
https://solr.apache.org/news.html#java-17-bug-affecting-solr ? Doubt it as you 
don't use much caching, but hotspot optimization of caches are disabled by 
default in 9.1. You could try to edit bin/solr script to disable the patch and 
see if anything is faster - risking a segfault crash instead :)
