Question about vulnerabilities and mitigations

I'm a proxmox beginner here, and just installed proxmox on a similar CPU: 'i7-3615QM'
It's a home system, and I was thinking of running pfSense in a container - as a kind of router-on-a-stick, as well as using it for some self-education.
The CPU vulnerabilities are:

Vulnerability Itlb multihit: KVM: Mitigation: VMX disabled Vulnerability L1tf: Mitigation; PTE Inversion; VMX conditional cache flushes, SMT vulnerable Vulnerability Mds: Mitigation; Clear CPU buffers; SMT vulnerable Vulnerability Meltdown: Mitigation; PTI Vulnerability Mmio stale data: Unknown: No mitigations Vulnerability Retbleed: Not affected Vulnerability Spec store bypass: Mitigation; Speculative Store Bypass disabled via prctl and seccomp Vulnerability Spectre v1: Mitigation; usercopy/swapgs barriers and __user pointer sanitization Vulnerability Spectre v2: Mitigation; Retpolines, IBPB conditional, IBRS_FW, STIBP conditional, RSB filling, PBRSB-e IBRS Not affected Vulnerability Srbds: Vulnerable: No mic

I'm concerned that it may be mitigated into uselessness. The first line, and the fact the IOMMU mapping is disabled concern me, but I don't know enough yet to work out if I'm wasting my time.

Cheers...
 
ran an iperf3 benchmark from ubuntu jammy container on proxmox to my workstation:

[ ID] Interval Transfer Bitrate [ 5] 0.00-20.04 sec 2.18 GBytes 934 Mbits/sec

2.3 % of CPU measured with top on host
