| - Please modify the macros to match your instance specifications and your workload. Recommended values are: | ||
| - `MANAGED_MEMORY_RECOVERY_THRESHOLD` around 65% of total machine RAM | ||
| - `MANAGED_MEMORY_THRESHOLD` around 75% of total machine RAM | ||
| - `UNMANAGED_MEMORY_THRESHOLD` around 25% of total machine RAM | ||
