You do not use port 80/443, so it does not have HTTP-HEADER (in theory).

service LB_port_451 {
    listen-address 10.1.1.1
    mode tcp
    port 451

Try to change to port 80 and check if it works.
You need another solution/configuration

Some highly unscientific tests (only did 3 reboots of each to rule out that any uncached data at the host would affect the result since I run this in a VM through VirtualBox 7.0) shows a difference of up to 2.1% improvment when having a config with 200 static routes.

Parent task is completed - Bugs will get their own subtask and linked to this parent if possible.

This should fix the hostname issue reported to BGP neighbors: https://github.com/vyos/vyos-1x/pull/2289

Perhaps a possible way to detect if the nic supports hardware flowtables or not.

Try to set sudo ethtool -K eth0 hw-tc-offload on.

If the result becomes:

Actual changes:
hw-tc-offload: off [requested on]
Could not change any device features

Then it doesnt support hardware flowtables.

Could also verify by reading the capability like so:

$ ethtool -k eth0 | grep hw-tc-offload
hw-tc-offload: off [fixed]

Perhaps a possible way to detect if the nic supports hardware flowtables or not.

Some feedback from the #netfilter channel over at libera.chat:

I got some funny results which I hope somebody else (with a faster cpu) are able to verify?

First tests unsecseful

Im guessing that what this task complains about has a huge part of the time it takes to complete smoketests.
