IT知识后端测试Redis

本文概述

  • Redis基准
  • Redis-cli
  • Memtier基准
  • RDB工具
使用以下出色的工具, 了解Redis的性能, 中断时间, 吞吐量, 数据传输速率等。
在过去的几年中, Redis(远程词典服务)的流行和使用量有所增加。
如何执行Redis基准测试（）

不仅适用于企业应用程序, 而且也适用于中小型企业。甚至, 你可以在WordPress上使用Redis进行缓存, 并且性能要好得多。如果有兴趣从头开始学习Redis, 请查看此在线课程。
作为企业应用程序的开发人员或系统管理员, 你应了解执行基准测试以了解应用程序的性能和容量。 Redis基准测试与Web服务器略有不同。好消息是, 有许多免费工具可用, 因此你可以选择最适合自己的工具。
准备探索吗？
Redis基准测试工具
  • Redis基准
  • Redis-cli
  • Memtier基准
  • RDB工具
Redis基准 利用Redis内置的基准测试实用程序redis-benchmark。它包含在Redis安装中, 只需在UNIX上键入redis-benchmark即可执行。它在Windows上也可用, 可执行文件是redis-benchmark.exe。
让我们来看以下示例。
针对192.168.0.100发送一百万个请求
[email  protected]:~# redis-benchmark -h 192.168.0.100 -p 6379 -n 1000000====== PING_INLINE ======1000000 requests completed in 30.62 seconds50 parallel clients3 bytes payloadkeep alive: 161.85% < = 1 milliseconds99.55% < = 2 milliseconds99.93% < = 3 milliseconds99.96% < = 4 milliseconds99.98% < = 5 milliseconds99.99% < = 6 milliseconds99.99% < = 7 milliseconds100.00% < = 8 milliseconds100.00% < = 9 milliseconds100.00% < = 9 milliseconds32653.06 requests per second

30.62秒内完成了100万个请求。还要注意最后一行, 每秒处理约32653个请求。
如果仔细看, 有效负载大小为3个字节。这是默认设置, 可以使用-d参数进行自定义。以下测试适用于有效负载为1mb的100k请求。
[email  protected]:~# redis-benchmark -h 127.0.0.1 -p 6379 -n 100000 -d 1000000====== PING_INLINE ======100000 requests completed in 2.80 seconds50 parallel clients1000000 bytes payloadkeep alive: 173.19% < = 1 milliseconds99.95% < = 2 milliseconds100.00% < = 2 milliseconds35676.06 requests per second

你注意到并行客户端了吗？它的默认值是50并进行调整, 可以使用-c参数。下面的示例适用于200个客户端。
[email  protected]:~# redis-benchmark -h 127.0.0.1 -p 6379 -n 100000 -d 1000000 -c 200====== PING_INLINE ======100000 requests completed in 3.77 seconds200 parallel clients1000000 bytes payloadkeep alive: 10.00% < = 1 milliseconds2.99% < = 2 milliseconds18.95% < = 3 milliseconds45.81% < = 4 milliseconds69.65% < = 5 milliseconds86.58% < = 6 milliseconds95.79% < = 7 milliseconds98.88% < = 8 milliseconds99.78% < = 9 milliseconds99.96% < = 10 milliseconds100.00% < = 10 milliseconds26532.24 requests per second

如你所见, 有200个客户, 这花费了更多时间, 处理速度也变慢了。但是, 这是意料之中的, 这有助于找到应用程序的真实性能。
对Redis基准工具不满意？不用担心, 还有以下内容。
Redis-cli 只对延迟信息感兴趣吗？
当然, 你可以使用Redis服务器随附的redis-cli。你可以使用– latency参数执行。
[email  protected]:~# redis-cli --latencymin: 0, max: 1, avg: 0.16 (1056 samples

缺省情况下, 延迟样本为每秒, 但你可以根据需要使用-i开关进行更改。
Memtier基准 Redis Labs的Memtier基准测试同时支持Redis和Memcache。它是一个高级基准测试工具, 具有以下各种测试选项。
  • 测试密码保护的Redis
  • 在集群模式下运行客户端
  • 提供客户端数量, 请求, 线程, 数据大小,
  • 调整设置和获取比例
还有更多……
这是一份快速测试报告。

我怀疑你是否可以在Windows上安装此程序, 但可以肯定在UNIX发行版(如RHEL / CentOS, Ubuntu / Debian, MacOS等)上进行安装。可以免费尝试体验。
RDB工具 既可以用作CLI也可以用作GUI。 RDBTools是一个跨平台工具, 旨在帮助提高应用程序性能。在谈到特定于基准测试时, 它具有内存分析功能, 该功能可以调查内存使用情况, 关键分析, 识别内存泄漏并建议降低内存使用率。
