## Analysis
|
|
|
|
### Throughput Analysis
|
|
|
|
**TCP Single Stream:**
|
|
- virtio: X Gbps (baseline)
|
|
- vhost-net: X Gbps (Y% improvement)
|
|
- macvtap: X Gbps (Y% improvement)
|
|
|
|
**Key Finding:** [Describe the performance differences]
|
|
|
|
### Latency Analysis
|
|
|
|
**P99 Latency:**
|
|
- virtio: X µs
|
|
- vhost-net: X µs
|
|
- macvtap: X µs
|
|
|
|
**Jitter (P99/P50 ratio):**
|
|
- virtio: X.Xx
|
|
- vhost-net: X.Xx
|
|
- macvtap: X.Xx
|
|
|
|
**Key Finding:** [Describe latency characteristics]
|
|
|
|
### PPS Analysis
|
|
|
|
**64-byte Packets (best overhead indicator):**
|
|
- virtio: X pps
|
|
- vhost-net: X pps (Y% improvement)
|
|
- macvtap: X pps (Y% improvement)
|
|
|
|
**Key Finding:** [Describe per-packet overhead differences]

## Conclusions
|
|
|
|
### Performance Hierarchy
|
|
|
|
1. **macvtap** - Best for:
|
|
- Maximum throughput requirements
|
|
- Lowest latency needs
|
|
- When host NIC can be dedicated
|
|
|
|
2. **vhost-net** - Best for:
|
|
- Multi-tenant environments
|
|
- Good balance of performance and flexibility
|
|
- Standard production workloads
|
|
|
|
3. **virtio** - Best for:
|
|
- Development/testing
|
|
- Maximum portability
|
|
- When performance is not critical
|
|
|
|
### Recommendations
|
|
|
|
For Volt production VMs:
|
|
- Default: `vhost-net` (best balance)
|
|
- High-performance option: `macvtap` (when applicable)
|
|
- Compatibility fallback: `virtio`
|
|
|
|

## Reproducibility
|
|
|
|
To reproduce these results:
|
|
|
|
```bash
|
|
# On server VM
|
|
iperf3 -s -D
|
|
sockperf sr --daemonize
|
|
netserver
|
|
|
|
# On client VM (for each backend)
|
|
./run-all.sh <server-ip> virtio
|
|
./run-all.sh <server-ip> vhost-net
|
|
./run-all.sh <server-ip> macvtap
|
