SpiceDB is an open source, Google Zanzibar-inspired, database system for creating and managing security-critical application permissions.

SpiceDB

We are running in kuberenetes, and CPU utilization is around 60%, memory is 30%, we suspect that caching is not working as it is supposed to be.
We are using the following configuration.
Is there anything else we should configure to increase the caching?
```
- name: "SPICEDB_DISPATCH_CHECK_PERMISSION_CONCURRENCY_LIMIT"
  value: "500" 
- name: "SPICEDB_DISPATCH_CLUSTER_CACHE_NUM_COUNTERS"
  value: "200000"
- name: "SPICEDB_DATASTORE_CONN_MAX_OPEN"
  value: "500"
- name: "SPICEDB_DISPATCH_CLUSTER_ENABLED"
  value: "true"
- name: "SPICEDB_DISPATCH_UPSTREAM_ADDR"
  value: "kubernetes:///spicedb.default:dispatch"
```
