Essentially make publish a zero alloc. Use c.mqtt.pp as the parser publish packet structure. Messages were initially copied because MQTT messages don't have CR_LF but was adding it so that it worked for NATS pub/subs and MQTT pub/subs. Now an MQTT producer sending to NATS sub will queue CR_LF after payload. Here is result of benchcmp for MQTT pub runs only: ``` benchmark old ns/op new ns/op delta BenchmarkMQTT_QoS0_Pub_______0b_Payload-8 157 55.6 -64.59% BenchmarkMQTT_QoS0_Pub_______8b_Payload-8 167 61.0 -63.47% BenchmarkMQTT_QoS0_Pub______32b_Payload-8 181 65.3 -63.92% BenchmarkMQTT_QoS0_Pub_____128b_Payload-8 243 78.1 -67.86% BenchmarkMQTT_QoS0_Pub_____256b_Payload-8 298 95.0 -68.12% BenchmarkMQTT_QoS0_Pub_______1K_Payload-8 604 224 -62.91% BenchmarkMQTT_QoS1_Pub_______0b_Payload-8 1713 1314 -23.29% BenchmarkMQTT_QoS1_Pub_______8b_Payload-8 1703 1311 -23.02% BenchmarkMQTT_QoS1_Pub______32b_Payload-8 1722 1345 -21.89% BenchmarkMQTT_QoS1_Pub_____128b_Payload-8 2105 1432 -31.97% BenchmarkMQTT_QoS1_Pub_____256b_Payload-8 2148 1503 -30.03% BenchmarkMQTT_QoS1_Pub_______1K_Payload-8 3024 1889 -37.53% benchmark old MB/s new MB/s speedup BenchmarkMQTT_QoS0_Pub_______0b_Payload-8 31.76 89.91 2.83x BenchmarkMQTT_QoS0_Pub_______8b_Payload-8 77.79 213.01 2.74x BenchmarkMQTT_QoS0_Pub______32b_Payload-8 204.52 566.26 2.77x BenchmarkMQTT_QoS0_Pub_____128b_Payload-8 550.65 1715.96 3.12x BenchmarkMQTT_QoS0_Pub_____256b_Payload-8 877.77 2757.16 3.14x BenchmarkMQTT_QoS0_Pub_______1K_Payload-8 1705.02 4607.72 2.70x BenchmarkMQTT_QoS1_Pub_______0b_Payload-8 6.42 8.37 1.30x BenchmarkMQTT_QoS1_Pub_______8b_Payload-8 11.16 14.49 1.30x BenchmarkMQTT_QoS1_Pub______32b_Payload-8 24.97 31.97 1.28x BenchmarkMQTT_QoS1_Pub_____128b_Payload-8 66.52 97.74 1.47x BenchmarkMQTT_QoS1_Pub_____256b_Payload-8 124.78 178.27 1.43x BenchmarkMQTT_QoS1_Pub_______1K_Payload-8 342.64 548.32 1.60x benchmark old allocs new allocs delta BenchmarkMQTT_QoS0_Pub_______0b_Payload-8 3 0 -100.00% BenchmarkMQTT_QoS0_Pub_______8b_Payload-8 3 0 -100.00% BenchmarkMQTT_QoS0_Pub______32b_Payload-8 3 0 -100.00% BenchmarkMQTT_QoS0_Pub_____128b_Payload-8 4 0 -100.00% BenchmarkMQTT_QoS0_Pub_____256b_Payload-8 4 0 -100.00% BenchmarkMQTT_QoS0_Pub_______1K_Payload-8 4 0 -100.00% BenchmarkMQTT_QoS1_Pub_______0b_Payload-8 5 2 -60.00% BenchmarkMQTT_QoS1_Pub_______8b_Payload-8 5 2 -60.00% BenchmarkMQTT_QoS1_Pub______32b_Payload-8 5 2 -60.00% BenchmarkMQTT_QoS1_Pub_____128b_Payload-8 7 3 -57.14% BenchmarkMQTT_QoS1_Pub_____256b_Payload-8 7 3 -57.14% BenchmarkMQTT_QoS1_Pub_______1K_Payload-8 7 3 -57.14% benchmark old bytes new bytes delta BenchmarkMQTT_QoS0_Pub_______0b_Payload-8 80 0 -100.00% BenchmarkMQTT_QoS0_Pub_______8b_Payload-8 88 0 -100.00% BenchmarkMQTT_QoS0_Pub______32b_Payload-8 120 0 -100.00% BenchmarkMQTT_QoS0_Pub_____128b_Payload-8 224 0 -100.00% BenchmarkMQTT_QoS0_Pub_____256b_Payload-8 369 1 -99.73% BenchmarkMQTT_QoS0_Pub_______1K_Payload-8 1250 31 -97.52% BenchmarkMQTT_QoS1_Pub_______0b_Payload-8 106 28 -73.58% BenchmarkMQTT_QoS1_Pub_______8b_Payload-8 122 28 -77.05% BenchmarkMQTT_QoS1_Pub______32b_Payload-8 154 28 -81.82% BenchmarkMQTT_QoS1_Pub_____128b_Payload-8 381 157 -58.79% BenchmarkMQTT_QoS1_Pub_____256b_Payload-8 655 287 -56.18% BenchmarkMQTT_QoS1_Pub_______1K_Payload-8 2312 1078 -53.37% ``` Signed-off-by: Ivan Kozlovic <ivan@synadia.com>
