Compulab fitlet-XA10-LAN Review: A Fanless AMD UCFF PC for Networking Applications

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.
