Hi all, I have a question.
I have athlon3200+ (2,2GHz) which is CORE router on which is PPPoE concetrator and right now there's constantly around 500 active PPPoE connections(25 Mbit). Processor goes up to 80-90% and I think it's time for me to buy new machine for that. I hesitate between p4 3,2 GHz and poweredge 2650 2x xeon 2,8 GHz. Which one can someone recommend? I have my doubts on this one with 2 processors since I saw in some posts that mikrotik OS is not very stabile with dual processor machine.

don't think too much about the processor speed, both are enough for 500 pppoe-connections.
but if the p4 3ghz is a self built one take the poweredge, its built for lasting and not only for speed, the board has better capacitors than any soho-mainboard and so on.
if the p4 3ghz is not selfbuilt and has good hardware in it, take it, as it is maybe cheaper.

hi, i don't need cheaper machine, I need beter!
now it is 500 PPPoE connections but in a few months it will be 1000 or 2000..., so I need hardware for it. Thanks

We tested a Intel Q9550 Quad Core PC and the performance was just astonishing by just using a single core. Get that one or something newer

What version of RouterOS?

Hi!

I recommend for you using intel core platforme and more than one core the version 3.7 , its working here with all 4 cores enabled as a pppoe concentrator and working perfectly . Here a /sys resou pri.. never crashed or needed to reboot. and with avarege of 500 simultaneous connections.

Thank you normis for your answer.

We have an MT router (Core 2 Quad 2.33 GHz and 2 GB RAM) running as BW Manager, and also doing NAT using http://wiki.mikrotik.com/wiki/Load_Balancing_Persistent as a guideline to src-nat our home users of over 4,000 to 250+ real IPs. Our total backbone is 70 Mbps and users' BW is managed using PCQ. We are having the same problems as others have reported about 3.15 becoming unstable after a while. In our case, it happens every 3 - 4 hours. We went back to 3.7 and it's working properly again, except that, occassionally some (around 5 - 10) customers would not be able to "ping" anything that goes through our router.

Since you've had luck in running 3.15 in your lab running on 1 core, would you suggest us to do it? Do you think the MT can take the load using only 1 processor core?
