Hardware Recommendations
* **Initial Setup:** Ensure that your initial hardware setup meets the minimum requirements for your expected campaign size. It's better to allocate more resources upfront to avoid performance bottlenecks.
* **Storage Planning:** Given the potential need for additional templates and the data generated by campaigns, planning for ample storage from the beginning is wise. Consider future expansion when selecting your hard disk size.
* **Use Built-in Tools:** Regularly utilize LUCY's [performance testing ](/application-reference/support/system-tests/performance-test.md)and [monitoring tools](/application-reference/support/status/system-monitoring.md) to keep your system running efficiently. These tools can provide valuable insights into how well your hardware is coping with the demands of your campaigns.
* **Flexible Scaling:** If you are hosting your LUCY instance on a VPS, take advantage of the ability to scale your resources as needed. This can be particularly useful for handling peak loads during large campaigns.
**VPS Hosting**
For users opting for a Virtual Private Server (VPS) hosted by LUCY:
* **Dynamic Resource Scaling.** LUCY provides the capability to automatically scale computing resources, including CPU and RAM, to meet the demands of your campaign. This feature ensures optimal performance of campaigns by adjusting resources in real time, eliminating the need for manual adjustments. In case of hardware limitations, users are encouraged to contact the[ support department](/contact-us.md) for assistance in scaling their Virtual Private Server (VPS).
