By default, the analyses in CodeScene are executed serially. That is, an analysis starts once the previous one has been completed. The rationale for the default behavior is to let CodeScene work well on limited hardware; the analysis might consume plenty of memory and CPU.
However, if you have enough hardware capabilities, you can run more analyses in parallel and optimize the overall analysis time.
Note that a change setting requires a restart of the CodeScene service in this case.
You also have to ensure you have enough system resources to execute incoming CI/CD delta analysis requests that will be processed in parallel with the analyses.
