# Other Considerations

- When assigning cores for EMS use, ensure that the Operating System does not schedule those cores for other processes.
- Assign cores on the same die if possible. This reduces cache sharing between dies. High levels of cache sharing between dies reduces memory performance.
- Hyper-threads are not real cores. Disable hyper-threading if possible. Do not assign cores to the EMS server such that it sets affinity for two "cores" that are actually sharing the same physical core by hyper-threading.
