perf-matrix.sh provides on-demand any-to-any performance testing:
- datanet: host-to-host bandwidth matrix over VLAN 1000
- guests: guest-to-guest (k8s/ultix VMs over datanet)
- storage: NFS read/write I/O per host
iperf3 installed on all 7 hosts (systemd service iperf3-server, enabled
but not auto-started) and all production VMs with guest-agent.
Also: tsys3 datanet persistence fix (USB NIC late-enumerate systemd
service), 4 missing reverse DNS zones created, netbird/ultix-mini/
ultix-sidecar/ultix-highside DNS records added (DNS now fully
consistent across all Tailscale nodes). [#413]

Perf testing results (#413):
- Host-to-host datanet: all 7 hosts at ~900-940 Mbps (1Gbps line rate)
- Guest-to-guest: all k8s nodes at ~920-1040 Mbps over VLAN 1000
- Storage I/O: NFS writes 27-65 MB/s (spinning disk), reads cached
Fixed tsys3 datanet: physical NIC enx8cae4ccda774 was DOWN and not
enslaved to the datanet bridge (config was correct but runtime state
was wrong). Enslaved manually, verified connectivity.
Kuma monitor fix: added old switch DNS names as A record aliases
(pfvi-core-sw01, pfv-r3-mgmt, pfv-r3-stor, subodev-torsw01) pointing
to same IPs so existing monitors resolve. Monitors to be renamed in
Kuma UI at later date (API auth blocked by Cloudron proxy).
