Tensorlake has redesigned its sandbox ingress path, moving a dataplane hop from a full L7 reverse proxy to an L4 forwarder utilizing kernel TLS (kTLS) and splice(2). This change was primarily driven by the need to optimize byte movement over an authenticated channel rather than application-level protocol understanding. The engineering team measured each change independently, finding that most CPU savings came from removing the L7 parser, with kTLS and splice(2) providing a smaller, additional throughput gain. AI
