By transitioning the Cloudflare One Client to use QUIC streams for Proxy Mode, we eliminated the overhead of user-space TCP stacks, resulting in a 2x increase in throughput and significant latency red
AI Summary
Here's a summary of the post in 3 concise sentences: Cloudflare rebuilt their proxy mode for the SASE platform, Cloudflare One, to improve performance by bypassing an inefficient TCP implementation and leveraging modern QUIC features. The new approach keeps traffic at Layer 4, eliminating IP packet handling and allowing for tunability to optimize performance. As a result, download and upload speeds doubled, and latency decreased significantly for users who require zero-trust security without sacrificing performance.
