Mmm, interesting no one type....

Check netstat -m make sure there's no buffer exhaustion happening.

Hi @aholmes5

I have the same issue. I connect my Fiber WAN on SFP+ 10G on netgate 6100 with a 10GTEK sfp+10G and my unifi switch on the second WAN on SFP+ 10G on netgate 6100 with DAC 10G cable but my download speed is reduce of 80% but my upload is fine.
Do you found a solution ?
