crs125-24g-1s-2hnd 100% cpu load when i am doing speedtest

Mon May 20, 2019 6:06 pm

Hello everyone.
I have one crs125-24g-1s-2hnd and one RB1100AHx4 Dude Edition.
They are connected between each other with Bonding with 2Gbps summary uplink.
So, when i am doing speedtest i have very strange results.
See link below.
For self-switch test:

From RB1100AH:

FW 6.44.3 on both devices.
LCD disabled, Wireless disabled too, fasttrack enabled on both.
Can you advise me with this situation?
Thanks.

See the comment in the speedtest result as shown in your screenshots.

CRS devices are intended to be used as hardware switches - they can do some routing and provide some services but the as CPU is not powerful you cannot use them to do wirespeed routing, for example.

In my case, i ma talking about uplink to upstream switch.
CRS device configured as switch without any routing or something else.
Is upstream limited to 200Mbps on Gigabit port?
Or i should configure some master port which will provide full speed?
Google showed post on this forum where CRS provides 1Gbps uplink with 60% load CPU

I'm currently doing load testing with CRSXXX devices.
Which command did you use to produce the above report ?

As tdw already stated, the issue is the CPU. It is written in red on your screenshot! The bandwidth tool uses the CPU to generate the traffic and the CPU is maxing out before it reaches the capable throughput. For a proper test, use 2 connected PCs to test the throughput.

Hello,

I've connected my CRS125-24h-1s-2hnd in my home to a ISP router (Huawei).
The configuration of Mikrotik is out of the box, so ther is no bridge config between does to routers - Huawei router is configured with DHCP for nomal hoome use.
Mikrotik is connected from his port 1 to ISP Huwaei router so basicaly there is a double NAT. I have fiber connection with 500/500 Mbps speeds and I only get
~350-370 Mbps download speed on my PC. I use only cat6 cables.

When I connect a PC directly to ISP Huawei router, the speeds get to that 500/500 Mbps... around 450-470 to be exact.

My questions is...
How can I speed up my bandwith through Mikrotik, because the ports should be 1Gbps speeds right?
When I do a PPOE connection, in a bridge mode, will that help - Routing and switching will be only done on Mikrotik then

Mikrotik has it's latest OS and firmware.

Thanks

CRS125 is a switch with low-capacity routing capabilities. If you look at test results under "Ethernet test results", you'll see what MT measured using some synthetic test suite. Many of forum users find the number in row "Routing - 25 ip filter rules" column "512 byte" pretty representative for real-life performance. And you're getting quite a bit better result.
