# Performance Impact

This health check identifies roles where `no_store` is explicitly set to `false`, which can lead to performance degradation if certificate volumes are high and CRL auto-rebuilding is not enabled.

**Health Check Name: `role_no_store_false`**

| `no_store=false` | If a role has `no_store` explicitly set to `false`, vHSM issues a warning. This can negatively impact performance, especially when managing a large number of certificates and when CRL auto-rebuilding is not enabled. |

#### **Recommended Actions**

* Update non-ACME roles to use `no_store=false`.\
  **Note:** ACME roles must have `no_store=true`.
* Set certificate lifetimes as short as possible to reduce the load on CRL and storage systems.
* Use Bring Your Own Certificate (BYOC) revocations to revoke certificates proactively when necessary.
