| From: Alex Volkov <avolkov@gmail.com> | I didn't run any tests but the Internet connection but the performance of | Raspberry Pi didn't seem to be any different than of any other router. The | USB controller is slow compared to modern x86 hardware, but as far as | embedded devices go, it's pretty fast. In theory, one reason that the RP is slow because so much goes through a single USB interface: all networking as well as all USB. | that combined with a single CPU that gets blocked on IO wait Generally under Linux a CPU does not get blocked due to I/O waiting. All processes might get blocked due to I/O waits, at which point the CPU cannot make progress because there is no work to do. But that's a slow I/O problem, not a slow processor problem. The RP does have a slow processor. I would guess that it would be somewhere in the middle of the pack compared with wireless routers' processors. But they have specialized hardware for networking (like a pair of ethernet ports and an ethernet switch). As always, performance guesses are unreliable (even mine!). Measurement is called for if it matters. --- GTALUG Talk Mailing List - talk@gtalug.org http://gtalug.org/mailman/listinfo/talk
