You should check if there is bottleneck in client side. I setup a 4.9.1 master/slave pair. 6 client send total 95000 TPS (produce and consume). The P99 of produce is 1.0 ms. All configuration is default. ``` # sudo sysctl -w vm.min_free_kbytes=10000000 # modify this carefully sudo sysctl -w vm.overcommit_memory=1 sudo sysctl -w vm.drop_caches=1 sudo sysctl -w vm.zone_reclaim_mode=0 sudo sysctl -w vm.max_map_count=655360 sudo sysctl -w vm.dirty_background_ratio=50 sudo sysctl -w vm.dirty_ratio=50 sudo sysctl -w vm.dirty_writeback_centisecs=360000 sudo sysctl -w vm.page-cluster=3 sudo sysctl -w vm.swappiness=1 ``` -- This is an automated message from the Apache Git Service.
