Performance Summary with Multiple Clients


With multiple clients, the limits are clearly set by the weak processor. Although we teamed the two Ethernet NICs up and configured them according to our managed switch, the NAS couldn't deliver transfer speeds over 100 MB/s. Actually, the measured speeds were much lower since the single core MarvelL CPU was struggling to keep up. That said, the NAS will easily handle the necessary load for home or SOHO since all clients will hardly ask for heavy data throughput at the same time.


As you can see, CPU utilization hit nearly 100% with simultaneous data transfers from multiple clients.
