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? -----Original Message----- From: Jan Høydahl <jan....@cominvent.com> Sent: 02 December 2022 10:14 To: users@solr.apache.org Subject: Re: Solr 9.1 performance WARNING: This email originated from outside of NHS Wales.

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 :) Jan > 2. des. 2022 kl. 10:11 skrev Joe Jones (DHCW - Software Development) > <joe.jo...@wales.nhs.uk.INVALID>: Rydym yn croesawu derbyn gohebiaeth yng Nghymraeg.
