SUSE Multi-Linux Manager performance depends on hardware resources, network bandwidth, latency between clients and server, etc. Based on the experience and different deployments that are in use, the advice for optimal performance of SUSE Multi-Linux Manager Server with an adequate number of proxies is to not exceed 10,000 clients per single server. It is highly recommended to move to the Hub setup and involve consultancy when you have more than 10,000 clients. Even with fine-tuning and an adequate number of proxies, such a large number of clients can lead to performance issues. For more information about managing a large number of clients, see Multiple Servers with Hub to Manage Large Scale Deployments. |

5.1. UEFI Secure Booting Requirements
Secure boot from the network using UEFI PXE or UEFI HTTP is supported on both SUSE Linux Enterprise Server 12 and SUSE Linux Enterprise Server 15. Booting from a hard disk using UEFI Secure Boot is fully supported on SUSE Linux Enterprise Server 15 images only.
You cannot boot SUSE Linux Enterprise Server 12 images using UEFI secure boot from a hard disk. This is due to limitations with the legacy Kiwi service. You need to either disable UEFI secure boot, or upgrade your terminals to SUSE Linux Enterprise Server 15.
