Hi,

I have some speed issue with my mikrotik.

Here are the speed test result.

ont 2.5Gbps → dac 10gbps → ccr2004 → sfp 2.5gpbs

speed test down 1,7Gbps up 550 Mbps

ont 2.5Gbps → dac 1gbps → ccr2004 → sfp 2.5gpbs

speed test down 950 Mbps up 550 Mbps

ont 2.5Gbps → dac 1gbps → ccr2004 → sfp 1gpbs

speed test down 950 Mbps up 550Mbps

ont 2.5Gbps → dac 10gbps → ccr2004 → sfp 1gpbs

speed test down 600Mbps up 550Mbps

ont 2.5Gbps → dac 10gbps → ccr2004 → sfp 1gpbs

speed test down 600Mbps up 550Mbps

My RouterOs is 6.48.

I try to replace the dac by an optic link, same issue

I also try to modify queue to ethernet, same.

Try 6.46.8 long term version

I just rollback to 6.46.8 LTS, and it’s the same issue …

Still stuck at 600Mbps at 1Gbps, and 1600Mbps at 2.5Gbps

Noboby have a guess ?

Hello, we you run your speedtest, check your cpu’s :

/system resource monitor

Maybe 1 is 100% of load.

Hi,

The cpu is globally at 5%, and no core are higher thant 15%
