“Encryption is slow, HTTPS can’t be high‑speed.”
Turns out, the bottleneck isn’t the math — it’s handshakes and memory copies.
Here’s what I did to make a single 1U Go server push 70–80 Gbps over HTTPS:
•
Switched to faster handshake signatures (ECC stamp instead of calligraphy)
•
Enabled cluster‑wide session resumption (no storm of new handshakes)
•
Cut out extra copies — pushed bulk encryption down the stack with zero‑copy I/O
