nsq 虚拟机测试（单个 topic）

测试环境

object	describe
cpu	2
memory	8G
nsqd count	1
nsqlookup	1
message size	1KB
message count	100000
topic count	1
channel count	20/100
client count	20/100

测试报告

channel count	write mb/s	write kops/s	read mb/s	read kops/s	per_channel_read ops/s
20	19.9	15.2	8.0	8.0	400
100	7.73	5.9	33.3	33.3	333

结果分析

测试结果与官方差距极大，仅达到每秒万级（已满足需求），官方测试报告能到达每秒十万甚至百万级，下面是结果误差较大的可能原因

1. 官方测试数据 client 并发低为 9/16/4，该测试 client 并发为 20/100
2. 虚拟机配置问题，2 CPU，会限制降低 client 并发性能
3. 测试数据为 1KB 大于 官方测试中的 0.1 KB
4. 官方的 producer 端为 golang 写的客户端，该测试直接使用 API 接口用 ab 工具发送 http 请求测试，http 连接创建销毁费时

测试脚本相关

启动 nsqd/nsqlookupd/nsqadmin

#!/bin/bash
readonly memQueueSize="${MEM_QUEUE_SIZE:-1000000}"
set -e
set -u

echo "# using --mem-queue-size=$memQueueSize"

if [ ! -x ./nsqd ]
then
  echo "Please copy executable nsqd here"
  exit
fi
if [ ! -x ./nsqlookupd ]
then
  echo "Please copy executable nsqlookupd here"
  exit
fi

echo "# running nsqlookupd and nsqd"
rm -f *.dat
./nsqlookupd --broadcast-address=127.0.0.1 >/dev/null 2>&1 &
nsqlookupd_pid=$!

./nsqd --mem-queue-size=$memQueueSize --lookupd-tcp-address=127.0.0.1:4160 --broadcast-address=127.0.0.1 >/dev/null 2>&1 &
nsqd_pid=$!

./nsqadmin --lookupd-http-address=127.0.0.1:4161 >/dev/null 2>&1 &
nsqadmin_pid=$!

创建 topic/channel

#!/bin/bash
readonly channelCount="${1:-1}"

echo "# using --channel-count=${channelCount}"

echo "# creating topic/channel"
for i in $(seq 1 ${channelCount})
do
    curl --silent -X POST "http://127.0.0.1:4151/topic/create?topic=topic_1" >/dev/null 2>&1
    if [ $i -lt 10 ]
    then
        curl --silent -X POST "http://127.0.0.1:4151/channel/create?topic=topic_1&channel=channel_0${i}" >/dev/null 2>&1
    else
        curl --silent -X POST "http://127.0.0.1:4151/channel/create?topic=topic_1&channel=channel_${i}" >/dev/null 2>&1

测试客户端代码
