I have a CRS305-1G-4S+ running 6.48.3. I can't seem to get anything more than 1gig despite having it auto-negotiated to a 10gig interface. The CPU skyrockets to 100% usage whenever utilizing a full gigabit, so it appears hardware offloading is not working despite being enabled. I tried messing around with Queues to get a higher-packet count queue size in case that could be an issue but that doesn't seem to change anything either.
What are some troubleshooting steps I can take to figure out what may be overriding the hardware offloading setup?

Re: Hardware Offloading Issue CRS305-1G-4S+
Good Morning,
I dont think the RouterOS Queues can't be HW-Offloaded on the CRS305-1G-4S+ , it always run on the CPU
There is an "Traffic Shaping" option available-->> https://help.mikrotik.com/docs/display/ ... s+switches

Re: Hardware Offloading Issue CRS305-1G-4S+
Do a /export hide-sensitive and post here.
If you plan to use it as a switch, not a router, this should not be a problem.

Thank you both for your responses. See below for the export of the config:

Re: Hardware Offloading Issue CRS305-1G-4S+
You need to re-configure for vlan filtering so that the switch will do hardware offloading.
Move the vlan interfaces to the bridge, and set appropriate pvid on untagged and set tagged vlan interfaces and set the bridge to vlan filtering. Then you can still run your dhcp client on vlan1
After this under /interface bridge port print you should get a H symbol to the left of the interface to indicate hardware offloading.
Your bridge export should look more like this.
