Eliminate network round-trips and optimize the kernel for high-speed packet delivery.
Reduce latency by allowing data transfer during the initial SYN packet of a TCP handshake.
Switching from CUBIC to Bottleneck Bandwidth and RTT (BBR) for higher throughput on lossy networks.
Scaling kernel network buffers to handle thousands of concurrent Apache connections without drops.
Zero-TCP latency isn't just about speed; it's about efficiency. By reducing the number of round-trips (RTT) required to establish a secure connection, we can cut TTFB for mobile and distant users by up to 40%.
