Toolbox containers inflict significant network performance impact on network perf

**Describe the bug**

I noticed severe network penalty using the default network/tap setup instatiated for toolbox containers On a 10Gbit connection to a NAS with 20G of bandwidth available to the fabric I am seeing toolbox throughput top out at around 3.5Gbit/s

Rootful distrobox of the same container runs close to line/host kernel rate

**Steps how to reproduce the behaviour**
*Create a toolbox container using fedora:latest tag - install iperf3 or similar tool
*Run iperf3 or similar on a target connected host OS which is able to saturate fabric
*run test from inside toolbox container to target
*repeat for distrobox/rootful container of same image
*repeat from host network userspace

**Expected behaviour**
Throughput should be roughly analogous for all three scenarios

**Actual behaviour**
toolbox containers top out around 3.5gbit
