ARMv7 server grade hardware does exist. It wasn't so long ago that I was helping the guys at Boston get RedSleeve 6 getting up and running on their Viridis servers: https://www.boston.co.uk/solutions/viridis/default.aspx The biggest limitation with 32-bit ARM hardware isn't the CPU performance but the 4GB RAM limit, and the vast majority of devices comes with far, far less than 4GB; 512MB-1GB is much more typical. If your workload fits within that memory envelope, I find the performance isn't too bad for a variety of workloads. Gordan
