<ul data-eligibleForWebStory="true"><li>A comparison was made between Turbo Streams and htmx's Server-Sent Events (SSE) to determine which delivers faster and more reliable real-time updates.</li><li>Turbo Streams, with its tight integration with Rails and WebSocket-based approach, showed higher latencies and server impact compared to htmx SSE, which scored better in terms of latency, failure recovery, and server resource usage.</li><li>Under load, htmx SSE outperformed Turbo Streams in latency metrics and auto-reconnect rates, largely due to htmx using HTTP/2 multiplexing and browser-reconnect mechanisms.</li><li>The decision to choose between Turbo Streams or htmx SSE depends on factors like existing infrastructure, the need for bidirectional updates, latency preferences, and implementation complexity.</li></ul>
