RB230 verses RB532

Thu Jun 29, 2006 5:32 pm

I have a RB230 that has 2 CM9s in it running 2 long range (15miles) connection and pushing about 6 megs average from the ethernet port.. cause it is connected to our internet feed

My CPU is running around 90%

when I look at the specs on the RB532, I see it is still a 266 cpu. If I switch to a RB532 will I expect to see the CPU go down? Or do I need to go with a 1gig mini-itx?

or maybe running at 90% is normal and ok.. but I dont think so.

That sure doesnt look normal to me.. I have 2 RB532s with SR5s shooting about 15-20 miles and my CPU maxes at about 20-25mb...

Which release of RouterOS are you using, have you tried an SR2/SR5 solution?

I am asking if the RB532 is better than the RB230.. it is the RB230 that is running high on CPU. I am wondering if the RB532 is more powerful in the cpu side, as it shows on the spec sheet it is still a 266

6 Mbps at 90% ? Alot of packets per second i assume?

I'm pretty sure you can get a bit more out of that unit but also i'm also pretty sure you have some problems in the network that cause that many packets...

Regarding topic (cpus). It is my uneducated opinion that RB230's cpu is "stronger" and even faster but it's bus/memory arch is one generation older than the RB500's. e.g. SDRAM vs DDR SDRAM.

The performance increase might not be that noticable with that many packets/second...

it is carrying about 400 clients, on 25 nodes.. this AP is at the front of the line, on top of the building that has our internet feed , so yea lots of packets.

so I get the feeling that I should go with a 1gig mini-itx

I would probably go with the mini-itx system. With that many packets / second you might want to run nstreme any all.

if ur running nstream on the rb230 that is where ur huge cpu usage is coming (that Plus the high number of packets).


on other thing to remember is that you can overclock the rb532 to 333mhz as im doing on 4 of them...with no issues/problems.


what are the results of a bandwidth test (perferably when there is no "other" traffic)

Those are based on XScale CPUs, which are not currently supported by MikroTik. And every question if those will be supported, was a clear "no" so far...

I get great bandwidth. I can pull 15 megs TCP, there is no noticable problem other that I see the CPU running high.
I feel like I am running my engine at full speed, which will cause failures faster over time.. unless I am wrong and running the CPU at 90% is no different than running it at 10%

Hi Allesio,

sorry, but I REALLY cannot imagine that this is correct. I read the page you quoted (in broken-Google-english ;) ), and it really references this Gateworks product. But this REALLY is based on a XScale CPU, and I am very sure that there is NO XScale version of MikroTik.

Perhaps someone from MikroTik could clarify this quickly?

Best regards,
Christian Meis
