NS2 vs Raspberry V2 performance comparison?

[raidsm]

Hi!

Just curious how is the performance difference between the NS2 and the raspberry v2?

NS2: kirkwood 800 arm V7 single core 256 RAM SATA interface
RPI2: ARM v7 4 cores 1Gb RAM USB HD

one of the benefit of the NS2 is the native SATA interface vs usb driven hard drive but someone know how it translate in real world performance? (web serving purposed , hard drive speed)

I'm using 4-5 service and my memory is almost full but my virtual memory is still unused. Maybe 1Gb RAM is overkill...

Anyone experienced both?

NWS2 = 1000 MBit/sec LAN IF
RPI2 = 100 MBit/sec LAN IF , the first bottleneck.
