The real bottleneck in Post-Quantum Cryptography (PQC) isn't CPU math—it's packet fragmentation at the network edge. Standard hybrid ML-KEM-768 payloads (2,272B) break the 1500B MTU limit, forcing multi-packet assembly and spiking p_{99.9} latency to 38.2ms. By utilizing geometric lattice constraints, https://secz6.oooooooooo.se compresses transit weight to 824B (sub-MTU). This keeps the p_{99.9} tail latency flat at 6.8ms under concurrent load.
