Relevant Versions: Artifactory 7 and above.
Artifactory comes with a predefined set of default configurations and parameters. The default Artifactory should handle up to ~200 concurrent connections well.
If you believe your Artifactory server is under-utilized, or in order to allow it to handle more processes at a given moment, it is possible to tune Artifactory to support a higher load.
While it is always possible to scale horizontally by adding additional nodes to your HA cluster, here we will focus on a more vertical scale.
Recommendation:
The more crucial Artifactory becomes in your organization, the more crucial will be to have a monitoring system to look over Artifactory.
