Re: Cisco 851 Throughput Question
If it helps, i have a Cisco 871 at home, doing PPPoE, nothing else. Bittorrent-wise it goes up to 26Mbps (~3.3MB/s). Nothing higher. Considering the 851 has the same CPU only half the memory, i'd say it will pretty much do the same. |

East Hanover, NJ | so my estimated numbers were pretty close huh, I said about 26 Mb/s and you get 24Mb/s.

I would go for at least an 871 for a 30Mb service especially considering the price difference.
Cisco stuff is much better made and much more sophisticated/versatile but if you just want a simple cheap router that will do the job 98% of the time don't buy a Cisco router, you will be wasting your money. |

| 871 is 2 1/2 times faster than the 851
25,000 PP/s vs 10,000 PP/s

CPU specs: »www.freescale.com/webapp/sps/sit···bTdG2977
quote:
Delivering an ideal combination of price, performance and low-power operation, the MPC8272 Family supports CPU frequencies ranging from 266 MHz to 400 MHz while offering the benefits of low power consumption (0.8 W at 266 MHz).
If you open up a 870 you'll see 266MHz printed on the CPU.
I don't have a 850 here but that CPU doesn't go any slower.
Maybe the ALTERA chip is different.
The 870 has an EPM3128ATC144-7N.

Can anyone look inside the 850? |

| I just opened the 851 cablevision gives you Same MC8272 processor marked 266/200/66Mhz same altera chipset.
I use an 871w with a fios 20/20 connection. I have switched my plans several times started with 20/5 went to 35/10 finally settled out 20/20 as the best for my needs the 871 has worked perfectly at all speeds. |
