Latency

What is Latency?

Latency is the time delay between when data is sent from a source and when it reaches its destination. In the context of the ON24 Platform, latency refers to how quickly information—such as audio, video, chat, or engagement interactions—transfers between presenters, attendees, and ON24’s delivery systems.

Measured in milliseconds (ms), latency is a critical component of webinar and event performance. A lower latency rate ensures smoother communication, real-time engagement, and synchronized content playback, while high latency can lead to noticeable lags, buffering, or out-of-sync presentations.

In digital engagement environments, latency can affect not only live streaming quality but also interactivity features such as polls, Q&A, and chat responsiveness. ON24 optimizes latency across its global network infrastructure to maintain seamless attendee experiences regardless of audience size or location.

Why it matters

• Improves real-time communication: Low latency ensures that live video and audio transmissions stay synchronized between hosts and attendees.
• Enhances audience experience: Reduces buffering and playback delays for smoother, high-quality streaming.
• Supports engagement tools: Ensures that polling, chat, and Q&A tools respond in real time.
• Maintains broadcast quality: Reduces disruptions during webinars, especially for large global audiences.

How it’s used

• Measure latency during pre-event testing to ensure stable data transmission before a live broadcast.
• Use high-speed, wired internet connections to reduce potential delays during webinars.
• Work with IT teams to optimize network performance by minimizing congestion and packet loss.
• Adjust video resolution or encoding settings to balance quality and latency for larger audiences.
• Monitor latency using webinar analytics to identify performance patterns across regions or sessions.
• Test interactivity elements—such as polls, chats, and reactions—to ensure latency doesn’t disrupt audience participation.

Key benefits

• Increases reliability: Keeps content delivery consistent and synchronized for all attendees.
• Boosts engagement: Ensures interactive webinar elements perform in real time.
• Enhances viewing experience: Minimizes audio lag and buffering for a more professional presentation.
• Supports scalability: Maintains stable streaming performance even under heavy attendee loads.
• Optimizes event outcomes: Reduces friction and distractions that can impact audience satisfaction.
