Troubleshooting performance issues

In case of performance issues, you may try the following:

• Review the hardware recommendations for SonarQube Server linked to Elasticsearch usage.
• Move the Elasticsearch storage to a storage with high IOPS and low latency: see Configure the Elasticsearch storage path in Installing the SonarQube Server from the ZIP file.
• Set the Housekeeping with a reduced retention time, to limit the database size.
• Configure the analysis scope to reduce the number of files analyzed, leading to shorter analysis and smaller database footprint.
• From the Enterprise Edition: increase the number of Compute Engine workers and/or configure the Compute Engine to enable parallel processing of pull requests and branch analyses for each project. See Compute engine performance. 
• For the Data Center Edition on Kubernetes: set up autoscaling.
• If performance issues occur after a PostgreSQL database upgrade, try reindexing the following database tables: issues, rules, and components.
