RB532 and Nstream2 speed test result

Mon Feb 13, 2006 8:24 pm

Hello,

we got on RB532 (333 MHz) in a speed test with NStream2 only 9 MBit/s fullduplex. We saw that the cpu was going to 95 %. The system was build up in the lab with 50 db RX/TX. Is that the performance the RB is able to do?

You didn't give us really much information about your test setup.

A quick test thrown together last week gave something about 23 to 27 MBit/s half-duplex using NStreme and WPA2 encryption between two routerboards. But as this was with bandwidth-test server and client running ON the respective routerboards (which alone eats significant CPU resources), higher throughput should be possible.
I think figures slightly above 30 MBit/s half-duplex should be possible using RB500s.

But tell us more about what you config looks like in this test - perhaps something else is using too much CPU...

If you really want to squeeze everything out of a point-to-point link using NStreme, be prepared to get something with more CPU power (like lets say 1 GHZ or more) - NStreme IS quite CPU intensive.

Best regards,

There must be something wrong with your setup, you should give some details.

Have you tested this fullduplex? Test-setup is very simple.

System is running in bridge mode (with routing we saw -1 MBps)
The BW-test client and the server are running on seperate pc's not on the RB.
On Half-Duplex (tested with netio) we saw results like yours but if you tell the BW-test-client to test both directions you see that the maximum bandwidth is limited to 9-10 MBps FDX. I will post the config in some hours ...

I know this is not the same thing as full duplex, but you could setup two links and then bond them so you have twice the speed and failover.
That is what I will start working on in the morning.
I was going to use Dual Nstreme but I think the speed of two Half duplex links will serve us better.
I didnt see anything better then 40/40mbps on the lab test using 3.2ghz PCs so I think it not for us at this time.

Hi, all the tests are in UDP or TCP? i need at least 50Mbps TCP of throughput in a RB532r5 PtP Link, any recommendation?
Thanks and regards!

I did the dual nstreme link. I just did a test and it's getting 35mbps on send and receive. But on both it only gets 22mbps on RX and TX which totals 44mbps. Keep in mind that the link has a lot on traffic on it at 2:00PM. I have a 2.4ghz card for TX and 5.8ghz card for RX.

I did have it running on 40mhz/turbo mode and it was almost double that speed. I think it was 65mbps send/receive and on both it was around 90mbps total

You are testing UDP or TCP?
