### Symptoms:

Some users have experienced performance degradation during deployments on JIRA Data Center.

### Cause:

This is usually caused by sub-optimal settings configuration which leads to unnecessary resets of the cluster in-memory cache.

### Resolution:

In [CMJ's Settings](https://apps.appf.re/dc/cmj/doc/General+Settings) page make sure the **Send ClearCacheEvent to clear Jira's internal caches after deployment **is not selected.
