Wireless Networking and Storage Performance
Networking and storage are two major aspects which influence our experience with any computing system. This section presents results from our evaluation of these aspects in the CompuLab fitlet-XA10-LAN. On the storage side, one option would be repetition of our strenuous SSD review tests on the drive(s) in the PC. Fortunately, to avoid that overkill, PCMark 8 has a storage bench where certain common workloads such as loading games and document processing are replayed on the target drive. Results are presented in two forms, one being a benchmark number and the other, a bandwidth figure. We ran the PCMark 8 storage bench on selected PCs and the results are presented below.
The Micron RealSSD C400v is a mSATA drive based on the Marvell 88SS9174 controller. It is quite old, considering that we reviewed it back in 2012. However, it does come with 25nm MLC flash, and is rated for a 36TBW workload. Practically speaking, it stands head-to-head with modern SSDs when it comes to performance for day-to-day applications.
On the networking side, we restrict ourselves to the evaluation of the WLAN component in this section. Our standard test router is the Netgear R7000 Nighthawk configured with both 2.4 GHz and 5 GHz networks. The router is placed approximately 20 ft. away, separated by a drywall (as in a typical US building). A wired client (Zotac ID89-Plus) is connected to the R7000 and serves as one endpoint for iperf evaluation. The PC under test is made to connect to either the 5 GHz (preferred) or 2.4 GHz SSID and iperf tests are conducted for both TCP and UDP transfers. It is ensured that the PC under test is the only wireless client for the Netgear R7000. We evaluate total throughput for up to 32 simultaneous TCP connections using iperf and present the highest number in the graph below.
In the UDP case, we try to transfer data at the highest rate possible for which we get less than 1% packet loss.
Since the WLAN adapter is actually an external USB 2.0 device and has a 1x1 802.11n 2.4 GHz-only configuration, it is not surprising to see that the Wi-Fi performance is barely passable. That said, the WLAN component is fine for use as a management interface (which is likely, given the presence of four gigabit wired ports). It must also be noted that the fitlet-X LAN sacrifices WLAN performance in favor of LAN due to lack of space. The fitlet-i, targeting more traditional use cases, incorporates Intel's AC7260 802.11ac chipset with dual antennae for significantly better Wi-Fi performance.

I was a bit surprised too, but, I think the reason is that the ERL might have hardware acceleration for NAT. On the other side, this is a full-fledged PC. It can do a lot more than just routing / I expect consumers might want to run more CPU-intensive network-related tasks in addition to routing duties.freeskier93 - Wednesday, April 20, 2016 - link
EdgeOS is Debian based and supports apt-get so you can install other things on it. Although it did bog down our connection a bit when someone was connected, our ERL ran OpenVPN good enough for occasional use.easp - Wednesday, April 20, 2016 - link
Not a big surprise, considering that ERL has hardware acceleration + tailored/optimized firmware. People running OpenWRT are often able to get a 50% boost out of much more modest with a bit of tuning of kernel parameters, so chances are, a little tweaking of the config would get closer to the max.trane - Wednesday, April 20, 2016 - link
A10 Micro 6700T may be the most underrated SoC in history. A couple of years back when it first released it was faster than Bay Trail across the board, and destroyed it for GPU performance. The Discovery tablet had good battery life too - I suspect within an hour or so of Bay Trail. Sadly, it got ambushed by Intel's Bay Trail contra revenues. Is this the first commercial design for it?It's surprising that it's still faster than Intel's latest 14nm Braswell, despite being on 28nm. Though yes, it does use a cTDP up.
I look forward to see dual-core low power Zen APUs in this market.

I was curious reading a review of this for over a year. Well, better late than never.Compulab - Wednesday, April 20, 2016 - link
Actually it was Compulab who held back the review. We had to improve the thermal characteristics of the product. Designing the heatsink and new metal panels and coating took a while.I think that the review reflects correctly the capabilities of fitlet, something we could not achieve sooner.

When you order the fitlet-LAN from amazon, does it have the new/improved black coating?serendip - Wednesday, April 20, 2016 - link
An x86 SOC that runs Linux out of the box? I think I just saw a unicorn. Too bad AMD couldn't push the Mullins chips to tablet makers. I'm stuck with an Atom tablet that will probably never run Linux with full support, thanks to 32-bit UEFI nonsense and closed source drivers.Compulab - Wednesday, April 20, 2016 - link
Actually Compulab (together with Linux Mint) has been offering pre-installed "MintBox" for several years now, including MintBox Mini based on fitlet.See http://www.fit-pc.com/web/products/mintbox/

Ganesh, thanks for writing this up. It was the first bit of exposure I've had with Compulab, and I'm very happy I found out about them. Their Airtop and Fitlab models are both very interesting products. Very very interesting.
