Solr 9.1 performance

Hello all, We currently have a Solr cloud set up under version 5.4.1 running on Windows. It contains 45 million records in a collection split across 12 shards with a replication factor of 2. The 12 shards are hosted across 6 servers running 4 nodes each. 3 servers are in one data center and 3

Re: Solr 9.1 performance

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 s

RE: Solr 9.1 performance

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? -Origina

Re: 8.11.2 Performance degradation

Hi Richard, when you mention "In particular which sparked interest, and so we spun up a parallel cluster with -Dsolr.http1=true, and there was no difference in performance. ", do you mean that you still see the degradation in performance right? I will probably state the obvious but normally you wo

Re: Solr 9.1 performance

What I'm saying is that 9.1 includes a workaround for the cache issues, see https://github.com/apache/solr/blob/releases/solr/9.1.0/solr/bin/solr#L2246-L2250 You may want to try to disable this workaround to see if it helps with the performance of your system. Alternatively try with JDK11, which
