By increasing the size of the intermediate buffer from 8k to 16k, perfomance of raw TCP forwarding is increased by ~19.4%. Performance was measured using `iperf` on local network. Direct: > 0.0000-10.0091 sec 120 GBytes 103 Gbits/sec Forwarding using `socat`: > 0.0000-10.0155 sec 39.5 GBytes 33.9 Gbits/sec Forwarding using `jetsocat` without this patch: > 0.0000-10.0016 sec 52.1 GBytes 44.7 Gbits/sec ~31.8% faster than `socat`. Forwarding using `jetsocat` with this patch: > 0.0000-10.0076 sec 62.2 GBytes 53.4 Gbits/sec ~57.5% faster than `socat` and ~19.4% faster than without this patch. Forwarding using `jetsocat`’s JMUX proxy (unrelated to this patch): > 0.0000-10.0519 sec 8.27 GBytes 7.07 Gbits/sec Using the JMUX proxy, even for a simple TCP port forwarding, is currently a whole ~86.7 slower than regular TCP port forwarding.
