Interestingly, they seem to be neck-and-neck at general packet forwarding performance, with the 3011 beating out the 1100 in certain scenarios and vice-versa in other scenarios.The 1100 has hardware IPsec acceleration in the CPU/SoC, which I don't think the 3011 has, so you might get better VPN performance on the 1100.The 3011 also has that spiffy color LCD on the front, too.But the 3011 has an SFP port, so if you need at least one fiber connection.They also both have two 5-port gigabit switch groups, but 1100 has 3 additional standalone gigabit interfaces.(Also, USB3 storage likely to be much faster than microSD on the 1100.) but the 3011 also has a USB3 port which can serve as a storage expansion port and more, while the 1100 has no USB support. The 1100 has a microSD internally for storage expansion while the 3011 doesn't.They are both very similar in that they are both all-gigabit, 1U-rackmount, dual-core machines.1100/AH has been around a while, and MikroTik has been working with its CPU architecture (PowerPC) a lot longer, and so should be more 'baked in'. There could be bugs and instability this early in the game. 3011 is a very new product, relatively speaking, and is also the first Routerboard of its kind (ARM CPU architecture).Probably depends on your requirements and your risk tolerance:
