RB493G

The RB493G has nine Gigabit ethernet ports, three miniPCI slots, and two switch chips, so the ethernet ports can be connected together in two switch groups for wire speed throughput.

The RB493G also has a USB 2.0 port and a microSD card slot for adding more storage or a 3G USB modem for backup connectivity.

The heart of this device is a high performance Atheros AR7161 CPU and it features 256MB of built in RAM. RB493G includes RouterOS - the operating system, which will turn this powerful system into a highly sophisticated router, firewall or bandwidth manager.

All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
