Hi Everyone, I am the mind, finger and soul behind another MQTT broker implementation, Mosca (https://github.com/mcollina/mosca). I have recently implemented the persistence support, and I am getting some weird numbers from Mosquitto (version 1.1.2).
*Mosquitto* $ ./benchmarks/single_pub_sub.js --header -q 1 -r 10000 mean, standard deviation, median, mode, runs 1317.389, 2621.9008969056513, 1088, 165, 10000 *Mosca* $ ./benchmarks/single_pub_sub.js --header -q 1 -r 10000 mean, standard deviation, median, mode, runs 208.6827, 252.84635984089678, 185, 170, 10000 It seems Mosquitto has some problem in scaling in handling many "unclean" subscriptions from different clients. In Mosca I am using LevelDB (through LevelUp) and I do not fsync, e.g. I allow some hypothetical packet loss in case of process crash. Let me know how I can help in fixing this. Cheers, Matteo
