Supermicro SYS-5018A-FTN4 A1SRi - Intel Atom C2758
I'm testing out a couple of these servers for use in remote sites as crashplan Proe servers + Content Filter (squid + dansguardian) + Misc other uses.  I've also used several of these boxes from Netgate as pfsense firewalls (C2759 Model).

• L2 Cache - 1024K -  25701 MB/s
• L3 Cache - None

Memtest86 5.0.1 Results

• L1 Cache 24K - 36923 MB/s
• L2 Cache 1024K - 30000 MB/S
• Memory : 16G - 5298 MB/s (42384 Mbit/s)

Streams
A single process can reach 5538 MB/s and 3 processes can hit 12465 MB/s, close to the theoretical max of 12800 MB/s of the memory.  Strange dip for 4 and 5 processes, probably because of which cores get used, the L2 cache is in 4 chunks of 1MB that are each shared with 2 cores.
