vm-to-vm network performance

### Description

For VZ type vms I see vm-to-vm `~25 Gbps` with bridged networked in both UTM and Virtuallbuddy for reference. This is tested via iperf3.
For lima it is `~1 Gbps` for bridged and` ~3.4 Gbps` for user-v2.
Is this expected?

Also while testing bridge vm-to-host iperf stalls after a short period and then access to bridged network subnet is stopped until vms is stopped and started.
And while stopping with limactl stop vm following error occurs:

```
ERRO[0002] [hostagent] Failed to read header read unix ->/private/var/run/lima/socket_vmnet.bridged: use of closed network connection
ERRO[0002] [hostagent] Failed to read packet EOF
```
This is Macbook Pro M1 with `macOS 14.4.1 (23E224)` and `limactl version 0.22.0` Trying to keep it short but I can share more info if required.
