Hi, We are migrating the solr from 7.2.1 to 9.6.0 in GCP and setup is done in GCP VM. [3 nodes for solr/3 nodes for ZK [6 VMs]]. While indexing the data in the solr 9.6.0 version, I noticed the indexing took 1 Hr 20 minutes for 47 GB data.
The same data took only 45 mins in the 7.2.1 version. Just to identify which version has issues, With the same data/same infrastructure/same schema and only difference is the solr config Lucene match version and tried the indexing in solr 8.6.0/9.0.0 still the performance is not same as 7.2.1. *Config used in solr 9.6.0:* - Lucene match version – - Tried 9.9 and 9.10 *Config used in the 7.2.1:* - *Lucene match version - *7.2.1 Please help to get the expected parameters or tuning parameters That I could have missed after solr 7.2.1? Are there any known performance issues in the indexing after the 7.2.1 version? Regards Sathish Ponnusamy
