SG-2100 WAN speed problem

@nocling Very good observation. The SG-3100 is definitely the optimal homeuse device for FULL use of a proper GigE internet connection.
I suspect your issue with the need to use the limiter is tied to the fact your Internet connection is asymmetrical. I see no such issues with my tests using SG-3100 on a symmetrical full duplex connection.
One has to remember that asymmetrical does not only impact return bandwidth, but also latency on reply/acknowledge traffic :-) Asymmetrical links are usually only half-duplex links, so once the link is "loaded" with download, the latency to insert return trafic becomes horrible - return traffic uses the same bandwidth and interrupts the download.

@keyser @NOCling Thinking back to my consideration in purchasing the sg2100 was it had 4gb of memory and the firewall limit was supposed to be 881mbps. The sg3100 only had 2gb of memory. For most of my projects, more memory was desirable. If the sg3100 had come with 4gb or an upgradeable 2gb, I might have jumped on it. The sg5100 was the one to "grow" into but I couldn't justify the price point for home use.
Also, does anyone know if the firewall speed limit on the sg2100 is a hardware or software limitation?

@alleykat It’s hardware. The CPU is a dualcore lowpower ARM CPU that does not contain a lot of horsepower.
It’s actually the same CPU as in the SG-1100, but because SG-2100 has two physical NIC’s (SG-1100 only has one), it’s capable of handling interupts from each interface on each CPU core and thus has a higher throughput than SG-1100
