Re: Performance of solr 9.3 vs 8.11

Are you asking a general question or did you see degradation and you are trying to dig into it? Some more details can help people understand the problem. There is this Jira[1] I filed about a specific type of degradation with highly distributed indices when using PKIAuthenticationPlugin [1] https

In 9 - The JVM security manager is enabled by default. That might be your issue. Disable via adding SOLR_SECURITY_MANAGER_ENABLED=false to your startup -Tim On Thu, Oct 12, 2023 at 1:54 PM Natarajan, Rajeswari wrote: > Hi, > > Does anyone see any query performance degradation from 8.11 to 9.3
