Elias Puurunen Shares Key Insights on Building Stable Low-Latency AV over IP Systems

AV technology expert Elias Puurunen recently shared findings from his deep dive into creating a stable, real-time AV over IP setup. His testing—focused on low latency and multicast performance—revealed that system stability depends on careful configuration, not a single “quick fix.”

Top Takeaways

• NIC choice matters. Older enterprise NICs can outperform built-ins—but only if properly configured.

• No single “go-fast” switch. Performance relies on the system working as a whole.

• A bad sender affects all receivers. Network stability is only as strong as its weakest link.

• CPU headroom ≠ performance. Frame drops can result from drivers, threads, or disk activity.

Elias’s research shows that a reliable AV-over-IP system comes from tuning every layer—from hardware to software—rather than relying on one upgrade or setting.
