kafka-producer-perf-test.sh 腳本命令的參數(shù)為：
--topic topic名稱，本例為test_perf
--num-records 總共需要發(fā)送的消息數(shù)，本例為1000000
--record-size 每個記錄的字節(jié)數(shù)，本例為1000
--throughput 每秒鐘發(fā)送的記錄數(shù)，本例為20000
--producer-props bootstrap.servers=localhost:9092 發(fā)送端的配置信息，本例只指定了kafka的鏈接信息
可以看到本例中，每秒平均向kafka寫入了16.92 MB的數(shù)據(jù)，大概是17737條消息，每次寫入的平均延遲為962.23毫秒，最大的延遲為7415.00毫秒，831 ms內(nèi)占50%
壓測消費消息
[root@kafka bin]# ./kafka-consumer-perf-test.sh --zookeeper localhost:2181 --topic test_perf --fetch-size 1048576 --messages 1000000 --threads 1
start.time, end.time, data.consumed.in.MB, MB.sec, data.consumed.in.nMsg, nMsg.sec
2016-12-24 09:18:26:409, 2016-12-24 09:18:36:231, 553.8979, 56.3936, 580804, 59132.9668
kafka-consumer-perf-test.sh 腳本命令的參數(shù)為：
--zookeeper 指定zookeeper的鏈接信息，本例為localhost:2181 ，如果使用新的純java客戶端則使用另外的配置
--topic 指定topic的名稱，本例為test_perf
--fetch-size 指定每次fetch的數(shù)據(jù)的大小，本例為1048576，也就是1M
--messages 總共要消費的消息個數(shù)，本例為1000000，100w
可以看到本例中，總共消費了553.8979M的數(shù)據(jù)，每秒為56.3936， 總共消費了580804條消息，每秒為59132.9668
大家在壓測的時候肯定不會讓壓測腳本和kafka服務器跑在同一臺電腦上，比較壓測腳本也要占用很多服務器資源，影響壓測準確性。如果沒有多余的服務器，也可以這樣簡單的執(zhí)行以下，了解kafka在你給定的硬件上的一個大概的吞吐量,本文由
